clip-share & vbulletin - login/pm/profile integration

Hi, I'm looking to integrate vbulletin and clip-share. I only want one registration page and one login for both the forum and video site. If you log into either you need to stay logged in to the other as well. The Private messages should be as one and well and viewing and editing profile information. Both vbulletin and clip-share should use 1 database. I have the vanilla/stock version install of both clip-share and vbulletin installed.
