Somone appears to have created a online storage and sync thing that actually works:
Dropbox - Home - Secure backup, sync and sharing made easy.
Few grips thou:
- It requires nautilus
- Not obvious how to create an account (it's not on the website, the client does it)
- The initial dialog box (which you use to sign up for an account) takes an age to appear
All that aside it works wonderfully, copy file into ~/Dropbox and it syncs automatically :)
… oh and it versions files too
… and only sends binary diffs
