I was at Seagate when they took over Lacie, ended up spending some time in Zurich with the team at Wuala. Very talented group of programmers, but had issues trying to keep out uploads from sanctioned country...and eventually killed off by Lacie
A startup called Space Monkey did something similar and is also gone. This seemed like a winning combination for users and backup providers, but in practice, itβs probably not practical to rely on users for redundant backup and file access.
the magic of wuala wasn't 'backup' but you were able to make communities quite easily about certain subjects with pretty good media sharing. I created one for collections of optical illusions and witty advertising campaigns.
