First, I am not a part of FTPbox team, just like this opensource project a lot.
It is somehow "DropBox-Like" service, but you make "the cloud" yourself using SFTP / FTP protocol. There's even a web interface available. The project is still in beta, but full program will also feature Windows, Linux and OSX client software, file encryption, handling of multiple accounts, selective sync options and more.
And now the best part. I wanted to donate, but there was only paypal donation button. So i emailed them and asked if Bitcoin donation is possible and they said: "NO PROBLEM!"
They also added the bitcoin address to their website.
Show these guys some love! : )http://ftpbox.org/about(BTC address is in the bottom right corner.)
