possible to have a local icloud?

I personally wouldn't want my photos and other personal stuff in apples cloud. Also at work we can't use dropbox etc so unlikely icloud either. Do you think it would be possible to use one of those airport & time capsules a local icloud at home?

My internet and mac is always on so I'd prefer to sync with that rather than the icloud.

update for anyone else interested in this, it does lan syncing at least.
