I have done this in the past (and actually, I'm playing with the
latest Python on eCos at the moment).  It's a non-trivial experience.
As mentioned previously, Python is very file oriented, so you need
a file system of some sort.  It's also not small - the version I've
been experimenting with is pretty big (which means ethernet downloading
is pretty much a necessity):
[gthomas@hermes Python-2.3a2]$ powerpc-eabi-size python 
   text    data     bss     dec     hex filename
1244460 1576988  701564 3523012  35c1c4 python

What sort of "prototyping" did you have in mind?  
What kind of functionality were you expecting to utilize?

BTW - I sent this reply using Python running on an embedded PowerPC
system running eCos :-)

Indeed - start with this :-)
