So we're talking about some LZO things such as snappy from google, and
that would be another run time dependency IIUC.

I think it's time to talk about fastlz:

  http://fastlz.org/
  http://code.google.com/p/fastlz/source/browse/trunk/fastlz.c

  551 lines of C code under MIT license, works also under windows

I guess it would be easy (and safe) enough to embed in our tree should
we decide going this way.

Regards,
