Rails - Jun 2006 - Sharing data between several Rails apps

Could anyone point me to some resources that explain how to share data 
between two Rails apps?

For example, say I have a wiki and a blog, as separate apps, and I want 
to be able to integrate them so the user seamlessly goes between the two 
on the same site. How do I pass user information between the two apps? 
Are rails session variables accessible to both apps? Do I have to pass 
everything as a parameter from one app to the next? Or should I create 
an overall "master app" and drop in the two apps as components (if 
that''s even feasible)? What''s generally the best approach or
technique?

Thanks!

Not sure what the best practices are, but I think components might be 
what you''re after.
