Nicotine supports "psyco", an inline optimizer for python
code, you can get it at http://sourceforge.net/projects/psyco/
Nicotine supports a country code blocker but that
requires a (GPL'ed) library called GeoIP. You can find it here:
C library: http://www.maxmind.com/app/c
Python bindings: http://www.maxmind.com/app/python
(the python bindings require the C library)
