Two Separate vB Forums One Mysql User Table

[Chris8]

I was thinking about creating completely separated vb forum (on other domain) and then connecting it with my first one using mysql views functionality to create virtual mirror of user database table replacing the second forum physical user table. So, users would need to register to the first forum and most things would be on the first forum but they would have an access to this second forum easily, same login same password. I also have a solution to deal with the cookies for seamless surfing both forums. The registration to second forum would be disabled.

My questions are, would it work? Is it possible? What problems it may cause if any? I wonder about it and I can't think of what could go wrong. I've read about other possible solutions of creating a bridge between two separate forum installations and this one seems to be easiest and most suitable for my purpose but I'm not sure if I will no run into any issues...

Any ideas if this would work good way?
