multi-site cart

Well, one of my friends just mentioned that I should be able to use the user-agent header information since that will be unique to each browser, and more often then not, if a user goes to site_a via their favorite browser (firefox, ie, opera, safari, etc, etc), they will also go to site_b in the same browser. That way, I don't have to worry about cookies, posted data, or anything like that. I guess I will have to use database session management, and when they start a new session, put the user-agent into session. If they go to another site, I'll check to see if a session entry in the db table exists with that user-agent, and if so, use that session rather then creating a new one.

Any thoughts? Any comments? Any wise-cracks?

Thanks
