Multiple Sites With 1 Database

[SirMoby]

For some reason I can't post in Pre Sales but perhaps this is a good place. One of my contact emails matches the one I have here but no matter.

I'd like to have VB running on different sites and share a single database. I'd like all the posts, users and forums to be the same but simply have a different skin for each site.

I understand that I'd need a VB license for each site and that's fine.

I already have a VB license and it's the best product so I'd like to keep using it. I know there are some phpBB hacks to do this but that's a security issue just waiting to be breached.

Is this possible?

Has it been done before?

What's the cost/pain threshold for it?

Thanks
