I’m using for my personal cloud Sparkleshare and I’m very happy with it. The 26 of May they released a new version (the 1.1) but for Linux you can get only the source code.
I have built for myself the binary package (using checkinstall) for Ubuntu and I put the link to download it here.
This is not the full fledged package (I’m using a 64bit environment, so may not work on 32bit systems…) but only a personal build, so your mileage may vary 🙂
I’ll use my version only until the official one will become available.
