VBulletin, Aspdotnewstorefront + Chat Login Intergration

Hey, We have a new site being launched soon. It currently has VBulletin which requires a login and our store which also requires a login. We are also planning to add a customer support script for chat, support tickets and knowledge base which will require a login. We are looking for someone to intergrate the logins between the three areas of the site. We have not yet picked a customer support script that we will be using - so that portion is open to suggestion. What we had in mind was [login to view URL] Thanks
