While unison is good (I use it all the time), it is no longer actively developed. See http://www.cis.upenn.edu/~bcpierce/unison/status.html

Least you think that unison is an "orphan" project, please read the whole of that page.

Unison is no longer under active development as a research project. At this point, there is no one whose job it is to add new features, fix bugs, or answer questions.

However, Unison is still widely used, and many readers (including the original developers are all still using Unison daily. It will continue to be maintained and supported for the foreseeable future, and we occasionally release new versions with bug fixes, improvements (sometimes large ones), and contributed patches.

The Unison developers also sometimes take on larger projects to add significant new features on a consulting basis. Contact Benjamin Pierce if you need something from Unison that it isn't currently providing and are able to pay to see it implemented.

Reports of bugs affecting correctness or safety are of interest to many people and will generally get high priority. Other bug reports will be looked at as time permits. Bugs should be reported to the unison-users@yahoogroups.com mailing list.

Feature requests are welcome, but will probably just be added to the ever-growing todo list. They should also be sent to unison-users@yahoogroups.com.

Patches are even more welcome. They should be sent to unison-hackers@lists.seas.upenn.edu. Since safety and robustness are Unison's most important properties, patches will be held to high standards of clear design and clean coding; feel free to ask for advice and feedback on unison-hackers. If you want to contribute to Unison, start by downloading the developer tarball from the download page. For some details on how the code is organized, etc., see the file CONTRIB.

A long time ago, I used to use rdist
   http://linux.about.com/library/cmd/blcmdl1_rdist.htm
to keep a bunch of DNS/DHCP servers in sync.

After a specified file was copied, you could have a special command run
to e.g. restart a daemon.

But, rdist didn't send incremental updates, and so I changed to a two-step
   rsync file
   ssh restart daemon
