I've come to the need several times that I would like a CB list downloadable.

Currently I've created a vCard field for my users, and it works as it should, however it's complicated for my users to copy out the list as text, save it and send it to the phone.
A plugin that grabs the list to download, and then specifies the name and extension would be awesome.

I was contemplating that it could be encoded in QR code, but QR code can't hold that much data, so only a single vcard can be encoded in qr code at a time.
