Not really. I just did a very simple hack to get Genshi working. I  
don't know it well enough by far to suggest some good patterns. All I  
know is that it should feel natural to Grok *and* Genshi developers.

Genshi uses the "push" model for templates (the view code pushes the  
data that the template needs into the template, rather than ZPTs  
fetching the data they need). I very much like "push". In Grok we  
typically have "semi-push" where the view class prepares data as  
attributes of self in update() and the the template accesses it as  
view.foo. So Genshi templates need to at least get the 'view' object,  
and the 'request' probably too. Perhaps 'context'. But really, I  
think everything else should be "pushed" in from the view class.
