Have never actually used or installed PEAK (though I did plumb through 
it's code looking for metaclass examples for a talk once), so no, wasn't 
aware of it.

Given that no-one has complained to Phillip yet (to my knowledge, backed 
up by the fact that it's still there), probably not ;) .

That said, as long as PEAK's module doesn't overwrite any of the modules 
in the PyDispatcher package (and as long as importing it's __init__.py 
doesn't completely kark up the object model in some inventive and evil 
way (this being PEAK, after all)), you should be able to continue using 
PyDispatcher... in other words, our __init__ file doesn't do anything 
special.

Please just go ahead and register your (infinite) disapproval, even if 
someone pipes up to say they've tried it ;) :) .  If it's a sub-package 
it really should be a sub-package, not a top-level package, if it's a 
competing global dispatch system, well, then, they'll just have to find 
a different top-level package name (or Phillip and I will have to rumble 
at PyCon (hope he's not a jujitsu master or something)).

Have fun,
Mike
