UDT implements its own congestion and retransmission algorithms, so using this
for VPNs would still give you all the problems decribed on this page:

If we are at a point where we can work on the transport layer of tinc, I'd
rather implement support for SCTP first.

I cannot quickly find a comparison between Matt's algorithms and Zlib or LZO
algorithms.  I will gladly accept a patch to support other compressors, but I
personally do not see much value in yet another one.
