So in particular, if the Tor Project wanted to make a pure BSD version, they would have to take out the NTRU parts. But I don't the Tor project wants that because then you'd have NTRU Tor clients and non-NTRU ones, the latter not being able to talk to the NTRU-enabled clients.

Another way for Tor to deal with the patent problem is to not implement NTRU until the NTRU patent expires in Aug 2017.

OK, that makes sense.
