I'm a bit lost with iDev implementation. Could someone give me some guidance?

I have iDev installed on a folder of the same server but how to implement my use case, I'm lost:

I intent to allow affiliates to offer certain discounts on subscription plans and get different returns:
eg. $30 reg price 10% discount: Price to customer $27 Commission to affiliate: $7
eg. $30 reg price 20% discount: Price to customer $24 Commission to affiliate: $4
eg. $30 reg price 30% discount: Price to customer $21 Commission to affiliate: $1

What I need:
1) Different promotions set up in CB Subs offering discount rates for each membership plan.
2) Somehow for these discount rates to be pre-selected depending on the landing page of the potential subscriber (or some other way??) so that the discount is evident from the start of the registration process.-this is the main challenge.
3) For these discounts not be visible for users who didn't come to the site via an affiliate.
4) To pass the discount used in a hidden field through the iDev CBSubs plug-in

Your guidance is appreciated

My idea was to create matching coupon codes in iDev and CB Subs. In iDev, the code would set the commission amount and in CB Subs the code would set the discount on subscription.

My idea was to create a function in iDev that combines each coupon code with their affiliate ID to create an individualised coupon code for each affiliate automtically. Something like TENOFF-BOBBY (Ten percent off price linked to affiliate Bobby). This is all iDev side, so not about CB Subs.

What needs to happen on CB Subs side:
When a user arrives at the landing page through a URL containing the coupon code a few things happen:
-A function breaks the code into the discount code (recognised by CB Subs later) and the affiliate code (to be sent back to iDev at the end). These two bits of data are stored in a session
-A message on the page confirms the discount available to them
-If the user registers, a function looks for an affiliate and coupon code in the session. If they are present, they are entered into hidden fields, and these two bits of data are sent back to iDev after successful payment through the iDev plugin.
-During registration, if no affiliate and coupon code are found in the session then a coupon field will be presented to the user which if populated breaks them down into an affiliate and coupon code as above.

What do you think? Do I have any chance of getting such a thing to work?

Sorry to bring this back up, but I'm still trying to figure out the best way to manage this.
I'm unsure of exactly what URL parameters are passed back to iDev in a CB Subs transaction. Can you clarify for me please.

I have set up a 'per product commission' in iDev (I assume that's the method) and set the price and commission rate. According to the iDev docs, this should be in a '&products_purchased=' parameter. I assume CB Subs sends the plan id not the name?? eg. &products_purchased=4 not &products_purchased=basicplan.
Can you confirm that there is nothing I need to do in this scenario within CB Subs to ID the affiliate who referred the user (as this is done through cookies on the shoppers computer placed through the link provided by the affiliate)?

I have also created corresponding 'coupons' in CB Subs and iDev. The purpose will be this:
-The coupon code will be entered as usual by the user in CB Subs at payment, and CB Subs will apply a 10/20/30% discount depending on the code.
-I somehow pass this code as one of the parameters within the iDev plug-in. iDev recognises this code and assigns the appropriate commission (I have this set up). In order to do this, can you tell me:
-How I pass the coupon code as a parameter (as it's not a #__comprofiler field), and
-The parameter that iDev is expecting for this code is '&coupon_code='. I'm assuming that I need to create a hidden field in cb field manager and use a auto action to get the coupon code entered in there??? I assume the url parameter sent to iDev is the field name, so how can I make this coupon_code instead of cb_coupon_code (I assume if I add it directly using phpmyadmin, this won't cause any issues with getting it to work with auto actions or being able to select it as a parameter within the CB Subs iDev plug-in configuration).
Your guidance (as always) is appreciated.
