Multiple forums single Member

[itsalltropical]

I have searched vBulletin.com and vBulletin.org and can't find anything that will do this. I asked vBulletin support and they referred me here. It's important to note that in addition to initial propagation I would like the Member to be able to change their profile in one forum and it propagate to the others.

If there is a mod already that does this please refer me to it.

Architecting new system right now.

I would like to enable members to register in one forum and have their registration info propagated to other forums ... so when they change passwords, avatars, etc it's done on all their forums. I know I can set up multiple forums within one image of vbulletin BUT I would like to architect it so that I use separate licenses (more money for vBulletin) but single Member name.

Now the vBulletin images will reside on the same server but different directories/URLs at FutureQuest.

Can this be done in vBulletin, add-on or a known hack? I am no where near writing hacks .... four days experience with vBulletin.
