Folders sync between macbook, MBL and PC

Need some advice from you…

I got 3 devices that I want to keep synchronized. MacBook, Win laptop and MBL itself. I want iPhoto and iTunes libraries to be syncronized as a folders to MBL and these folders should be accessable by PC via my home wi-fi network. Or in another words I want my Mac photos and music to be syncronized as a folder to my PC via MBL (hope this sounds better :-)))). For PC I used SyncToy and it perfectly copes with its functions. But want can I use for Mac?

Thanks!

I use rsync.
