Well, if it only takes 2 compromised nodes in a circuit to compromise
that circuit, then Tor isn't really useful for anything other than
keeping your IP address out of server logs.  That's fine, as that's
all I use Tor for anyway, and it works well for that limited purpose. 
I just thought there was more potential.

Anyway, as I've said in my other post, I need to delve a lot deeper
into the design information.  I should probably build my own client
while I'm at it - to really understand what's going on.

Thanks for your help and information.
