Integrate vbulletin login / session info sitewide

[zeropaid]

Hi, I know there are robust hacks out there that will do this and more, but I am looking for something extremely simple. What I want is a snippet of code I can include on all the pages on my site that are outisde the forum that will :

a) recognize a user as logged in, start their session, add them to the who's onling list, and show some stats, like:

There are 297 users online, 45 members and 252 guests

b) not recognize a user as logged in, start their session, and present them with a login box and some who's online stats

I also need to be able to grab this user's userid for use in other applications, so that either needs to be a session variable I have access to or a cookie or something once they are logged in.

Please let me know if there is an exisiting hack for this, if not I will pay for one.

Thanks,

Chris
