This wouldn't really fix this problem, though because if $HOME is still 
on your sys.path then the module would be picked up from there anyway, 
right?  

Regarding PEP-328, my understanding is that the -dot- notation needed 
for sub-packages only works in Python 2.4, so we can't use it now unless 
we drop support for Python 2.3 (or play ugly games with version 
checking...) which I don't think we should until PEP-328 actually does 
get enforced.
