People move in crowds, and although the initial draw to Ruby was  
Rails, that translated into "Ruby is the next Java", which is a force  
to be reckoned with in and of itself.

I think the fact that Ruby doesn't have a Java library migration path  
is exactly why JPype is a great opportunity for Python.  Django and  
TG will not (regardless of their technical merits) catch up to Rails  
in terms of broader mindshare for years, if ever.  Having them (and  
pylons! :-) is obviously fantastic, but opening up a new front of  
comparison where Python is the obvious choice is where Python can  
score points, rather than try to catch up.

You bet, Jython is a great concept, and it's another arrow in Python  
quiver.  I don't think it comes close to nullifying JPype's potential  
to help Python's stature with Java developers, though -- it's  
orthogonal to JPype, and therefore complimentary.
