Hi,
could this library not be used to solve the NAT Traversal problems?

Presumably you mean to have the tahoe node figure out the public IP
address it is behind, and to be able to advertise that. That sounds
like the right approach for servers with deficient (NATed) IP
connectivity.
As an aside, it is bad form (gratuitously unportable) to write bash
scripts. Presumably one could write a sh script, following POSIX sh
standards, and such a script could be properly executed by any
POSIX-compliant sh implemntation (bash, dash, NetBSD's /bin/sh, etc.).
(I'm not sure what you meant about not needing portability because of
Pi; note that NetBSD with it's own non-bash POSIX sh runs on the Pi
hardware, in addition to GNU/Linux. Presumably FreeBSD does as well.)

For now, I think you do. There's a pending discussion about having the
introducer use the IP address that it sees for the incoming connection.
