I would release my code under any license that suits Wei or the CryptoPP
project, I wouldn't mind, though I'm a real GPL-lover ;)
If anybody could ensure me that I wouldn't break Europe/Belgian patent
law, I could easily maintain the NTRU-supported-branch.

Just make sure to keep strait on the difference between
patents and copyright.
The code is protected by copyright. The ones implementing
it should never see the GLP-code, just implement it from the
specification of the algorithm. Then somebody else may write
unit tests to compare the new implementation to the GLP one.
Then there is no way to claim the new code is tainted by the
GLP-code and you can use any licence you see fit.
The algorithm itself may be encumbered by patents in some territories.
If you are somewhere this patent can not be enforced you are golden,
if not you really have no other option than to pay for a patent-license.
Unless you find a way to invalidate the patent, but that would most
likely require quite a lot of money in lawyer-fees.
If the project can be kept out of range of the patent holder the ones
using it may have pay for a license if they are where the patent may
be enforced.
On the other hand, if the ones holding the patent have given a
generic license to the GPL-implementation, they might be willing
to give a license to another open-source implementation.
It could be worth it to discuss it with them.
Just my two cents.
