Is there any software available, or might there be, for Maemo which allows for syncing of folders.

I´ve searched but cannot find....

What I see as being very useful is:
- Selecting folder A on my N900 and pairing it with folder B on my work´s shared drives and folder C on my laptop so that the program could be run to synchronize those together.
- Another use is syncing part of my mp3 / picture collection on the home network server automatically with the N900. Telling it to compare folder A there with folder B on the device,


Anything such as this available?
