I dont know what the problem was, but if you share your algorithm and the problems you encountered I believe we can solve the problems.

I would structure the hack like this:
* a seperate table that saves custom post bits.
* Code to post new postbits (invisible/moderated) and Admin CP integration to add/edit/approve (make visible) these new postbits
* User CP modification to give the users the right to choose their postbit. ($bbuserinfo[postbit])
* functions.php modification to check if $bbuserinfo[postbit] is set, if yes get the postbit from custom table to apply, if no/or invalid/unallowed postbit get default one.
You can use the function in webtemplates hack to get/parse a custom template from a custom table.

Needless to say anything I can do, I'm ready for help..
