In case there is anyone who wants this functionality now and is impatient to wait for the properly coded version, i have managed with a small edit to create blanket rules for tabs using the privacy plugin.
There are two pretty simple stages;
First (or second, order doesn't mnatter) it requires entering into the database (unless you know how to set tabs without doing this, not all have edit tabs). Just enter into the #_comprofiler_privacy table a rule for each of the tabs you want (you need their id numbers) for instance;
userid = 9999
type = tab
xid = 44
Rule = 2
params = *leave blank*
Where 9999 is the user id number we are using
tab is the type of rule (i assume there is also field option here but don't need it myself)
xid is the tab id number
Rule 2 is the one for friends/connections only.
You will need to make one rule for each tab changing only the xid field to reflect each tab you want hidden.
Secondly, you need to make a minor edit in the cb.privacy.php file (in the usual place

), and adjust the line (which is number 56 on my machine);
[code:1]$uid = (int) $user->id;[/code:1]
to reflect the rule that we just made for our ficticious (or not) 9999 character;
[code:1]$uid = 9999;[/code:1]
Then, well nothing, that is all!
it works great and evry tab I assigned is now only visible to connections on my site (which is just what I wanted!).
Many thanks for this Beat, Nant and the team!
[of course back up everything, even though it is a minor edit]
best to all,

[EDIT] - on further inspection, due to technically 'all users' being user 9999 according to the privacy plugin in this hack, it means that any user saving a setting would over ride the entry we inserted. So in my version I have commented out all those lines that are part of the 'delete' and 'save' functions (delete wipes the entry for that user in the event of null entry and save updating over the entry i think by my (poor) reading of the code. I have attached this file if anyone wants it (will be pointless when the newer version is released by the team, but I want this functionality now as I have waited for this since my first joomla).
