I know there's no patent on it, and other people have done implementations.
The "resources" page on rsync.samba.org points to a REXX implementation.
Josh Macdonald wrote an implementation in C
and Martin Pool has turned it into a library in C (I don't see where the
home page is -- Martin?).  I believe somebody else had talked about a java
implementation but never actually did it.
