Thank you!

I am planning to add tree hashing (Merkle tree) to speed up partly
received files checking.

I am subscribed to your blog. Yep, interesting things you write.
I have got similar, but on russian language :-).

Fixed it quickly in: http://www.git.cypherpunks.ru/?p=nncp.git;a=commitdiff;h=36953cde29afd58982caf2327d3dbe5bf5242256
Current messages are a long-time mess already. Seems that the first
thing I should do is to clean all of them and make a clear strict scheme
for each possible message. That should prevent that kind of errors when
some fields are missing.

I think that configurable option for handshake timeout is easy to add.
Handshake timeouts are just hardcoded, that is not right.
If you do not need some kind of anonymity, then Yggdrasil works pretty
well with very low overhead and relatively low latencies. I have not
touched for years, but remember that liked it much. Very easy to setup
overlay network, where even NATed nodes can communicate through the
other ones. cjdns was very unstable when I connected to Hyperboria.
