It's a good question. That's the next thing we need to think about. 
We're going to need to mess around with the publication process. It may 
be we need to make a big step there to support this, but I want us to do 
some serious thinking about publication anyway.

Note though that if we wanted to *hack* something we may be able to get 
it working by changing publication.py in Grok. That wouldn't work with 
grokcore.View though, only with Grok. And I'd rather actually get rid of 
that stuff somehow rather than extend it with more complication if at 
all possible.
