Since I've realized windows xp's firewall can't block outbound traffic, I need a lightweight solution to block a specific app.
Something along the lines of "little snitch" on OSX would be a great, but I can't find an alternative.
I really wanna avoid running a bloated firewall ala zone alarm for doing just this, so maybe there are lighter weight solutions around…
Know of a lightweight and fast application for this ?

That would be as lightweight as it gets (memory footprint of both programs: around 5MB):
CurrPorts is freeware and portable (no installation required).
If you're looking for a 'real' firewall application for XP, have a look at iSafer (a portable version is available here).
iSafer is free open source freeware.
