To integrate the two applications I used nusoap which is a common tool used to communicate between applications (can be on different servers) integrate vbulleting with other applications. You create functions in each application eg create acount in vbulletin and just call it from oscommerce or vice versa. You just have to work out how the function works in the application ie you have to look thru the source code in vbulletin on how it creates an account. But what I created for country bumpkin is very specific for their needs and will not necessarily suit your requirements. Also at the moment you have to login to both applications but with some extra work I am sure that one login can be used to be logged into both applications.
