[Pythonmac-SIG] Python solution to monitor your internet connection?

[Bob Ippolito]

Well I only downloaded it to see how it worked (pick it apart ;) .. I 
don't personally use a whole lot of software that tries to spy on me, 
but I have friends who do (thanks, Macromedia!) and they say that it 
works just fine.

Technically, I would certainly recommend it.  It seems to work as 
advertised, easy to use, etc.
Personally, I would like to see an open source version (for study, not 
to prevent obdev from making money), but I'm not interested enough to 
write it.
