+1 !

Unless Apple has really broken things (and they usually don't in this 
way), that should be fine.

However, a potential arise when folks want to build their own extensions 
against the python.org (and numpy) binaries.

As I understand it, you can not build extensions to the 32 bit 10.3 
binary on Lion, because Apple has not distributed the 10.4 sdk with 
XCode (nor does it support PPC compilation)

But I think the 10.6+ binaries are fine.

( wish we had 10.5+ Intel only binaries, as I still need to support 
10.5, but there are reasons that wasn't done)

No Lion here just yet, so I can't test -- hopefully soon.

they'll work (the 10.6, not 10.7 is because 10.7 didn't exist yet) -- 
with the exception of the above, which is, unfortunately, a common 
numpy/scipy use case.
