As far as I know, these are all still active, although possibly experimental:

Pynie               (Python for the Parrot VM)
WPython             (16-bit word-codes instead of byte-codes)
HotPy               (high-performance optimizing VM for Python)
Skulpt              (Javascript implementation)
HoPe                (Python in Haskell)
Berp                (another Python in Haskell)

WPython in particular seems to be very promising, and quite fast. I don't 
understand why it doesn't get more attention (although I admit I can't 
criticise, since I haven't installed or used it myself).


In the Java world, there are byte-code optimizers such as Soot, BLOAT and 
ProGuard which apparently can speed up Java significantly. As far as I can 
tell, in the Python world byte-code optimization is a severely neglected area. 
For good reason? No idea.
