The free tracks have DRM so yes, I think they can be tracked. They can even
be disabled for any reason, according to their humourous yet hostile EULA.

If ever you want to kick up the performance grab the b25 beta. You can
download from up to 50 sources instead of under 20 and you can shift it into
ultrapeer mode (connecting to 18 Bears and 8 Limes) so your searches get a
lot of traction too.

Since it also gives you plenty of info (much more than v6 or any version of
LimeWire) you can also weed through thickets of worms and fakes quite easily.
It was probably that unique ability alone which prompted the RIAA to sue Free
Peers and force them to sell it to their friends at iMesh so they could replace it
with their crippled iMesh software in disguise.
