Sorry for th elate reply, I was pretty stressed out due to the
Supercomputing Conference lately.

yes and no. The full source code is available at:
http://archiv.tu-chemnitz.de/pub/2006/0025/data/enet_module_btl.tar.gz

It consists of a kernel module implementing the low latency sockets and
a BTL for Open MPI that uses those new sockets.

However, this is a stable version that does not have flow control. A
newer version of the code with flow control (which is still being
developed/potentially buggy) is available on request only (ask me if you
are interested to test it).

Best,
  Torsten
