The best solution for this kind of stuff that I know is using dropbox. You will need an internet connection to upload the md5 hashes to the dropbox server, but after that files will sync over the LAN.

However, the newer versions of the Linux kernel include a feature called FS-Cache & CacheFS, which sounds exactly like what you (and I) want.
