I suggest using Viewlets attached to a Viewletmanager.  I am just
learning about these myself but it was easy to see how you can
communicate between Viewlets.  

I recently did a remake of a Grok tutorial on viewlets:
http://grok.zope.org/documentation/how-to/understanding-viewlets

that demonstrates something that might help you out.  Unfortunately they
haven't published it yet but if you have a login on grok.zope.org I
think I can share it with you.  I'll also send you the code via email if
you wish.

Cheers,
Tim
