After reading that excellent article, yes, that is what I mean.  I want to use 
Donovan Preston's LivePage technology, which is described in a link from tha 
article, under Zope3.

I'm not sure what issues are tricky, but LivePage uses a 
?id=<sessionid>-<incrementingconnectioninteger>, rather than just the session 
id, so that you can have the same page open in multiple tabs, each with their 
own link back to the server.

I'll consider that, if there is interest.  I think Ajax support is pretty 
important these days.
