wpython has reached 1.1 final version. If you are interested, you can find
it here: http://code.google.com/p/wpython2/ and you can download the new
slides that cover the improvements over 1.0 alpha.

Did you used wpython wordcode format, or a new one?

Yes, you're right. wpython approach is to encode as much information as it
can to save space, decoding time, "specialize" some opcodes, etc..
