There was some similar example available with pre-0.9.0 versions. I was
too lazy to update this to latest release and preferably move it to
userspace. You may find it currently in the SVN version under
examples/broken/round-trip-time/{multi-client,server}. Sorry, if you did
some work twice now, but I will look at your code, maybe it's already
what we need to re-enable this test case.

Broadcast packets are not looped back. You may either send your packet
to some rtlo-assigned route or to an outgoing interface, but not both
automatically at the same time - at least not yet. One may consider to
add a feature for duplicating outgoing packets if there are multiple
matching routes. Just takes someone to hack it.

I'm not a fan of the showroom concept, it's tricky to find for most
users, and someone has to maintain it *additionally* to the main example
code base. I would rather prefer patches to add new or re-enable broken
examples in the main repository. The smoother those patches are to
integrate the faster they will become publicly available. Or even
better: is there someone willing to become an examples maintainer? SVN
write access is quickly set up. ;)
