I’ve been looking for Dropbox opensource alternatives. I wish to install my own linux server with a shared repository and clients accesing from windows, mac, ipad (IOS) and android devices.
I’ve been testing Sparkleshare, but there is no client for Windows XP and it hangs when there are changes in a big number of files at local repository.
Also I’ve plans to test syncany that seems to be in the good path but is not mature yet.
Now I will have a look at owncloud, that also has business releases with maintenance support plans.
