Have a work-in-progress patch series for lcsync:

  https://librecast.net/lcsync.html

  Librecast file and data syncing tool.
  Compare data with merkle trees, sync via multicast.

blockers seem to be:

* issues around test suites

* not knowing the appropriate place or way to run "setcap
  cap_net_raw=eip bin/lcsync" ... setuid root would not be appropriate
  as that would allow overwriting nearly any file on the filesystem.

Will send patches shortly, one for the librecast library, and one for
lcsync itself.

live well,
