Hey, thanks Jeff. Less magic was what I was looking for in my original
post. If my View Class is going to end up having BrowserView in its base
classes, I want to see it in the class definition, for exactly the
reasons you stated.

 For having understandable code I think that's much more important than
'getView' vs 'getMultiAdapter'.

I had done a fair amount of searcing through the code, API docs and
mailing list, and both books, and up until now had not known than
IBrowserView was where the 'context' and 'request' attributes were
coming from. Feel like I'm having one of those "I was absent that day"
episodes. Thanks for the excellent clarification.
