busy, or reading their email off-line, could you give us a one short
paragraph description of what it is?
Actually, since I'm none of the above, I'll answer my own question:
WPython is an implementation of Python that uses 16-bit wordcodes
instead of byte code, and claims to have various performance benefits
from doing so.
It looks like good work, thank you.

Hi Steven,
sorry, I made a mistake, assuming that the project was known.
WPython is a CPython 2.6.4 implementation that uses "wordcodes" instead of bytecodes. A wordcode is a word (16 bits, two bytes, in this case) used to represent VM opcodes. This new encoding enabled to simplify the execution of the virtual machine main cycle, improving understanding, maintenance, and extensibility; less space is required on average, and execution speed is improved too.
