Perhaps this is a better example: Most large-scale open source products
such as Firefox and MySQL are built with reused SW components which may
different licenses from the main body of the project's code.
I don't see how TrueCrypt is in any way unique in this
regard. For TrueCrypt original code, you should consider a license
(Apache 2.0 seems like a good choice) which restricts downstream users
from employing your trademarks without permission, and writing a README
or COPYING file which spells out the licensing on
all the reused SW components.
