I tried Wuala a couple of years ago and ended up dropping it because, if I recall, their Android client was slow and/or ugly. It’s interesting that they have a dual-key encryption scheme to allow sharing—- that’s what I think mega.com is doing too. Theoretically dual-key will be unbreakable (absent brute force) if nobody except the expected recipient gets the public key. See Wikipedia if you are interested - it’s really cool stuff. But in practice most dual-key systems do you the favor of saving your public key for you so they can transparently decrypt your shared files for your recipients. Obviously if a provider can encrypt a file for your share recipient, they can also decrypt it under subpoena. Switzerland is a signatory to the Hague convention and thus will allow US litigants to compel the production of documents from Swiss companies (with the exception of banks pursuant to the Swiss Banking Privacy Act).
