It's interesting, this use case sound pretty close to what I'm talking 
about in the very last part of this message:

http://mail.zope.org/pipermail/zope-dev/2009-March/035220.html

ie: adapter context based on object traversal rather than notion of 
"current site".

Can someone confirm to me whether or not manually specifying the context 
as I have in the example above would work, or would I need to do:

 >>> adapter1 = getAdapter(a,ISomething,context=siteA)
 >>> adapter2 = getAdapter(b,ISomething,context=siteB)

cheers,

Chris
