Special remote support for [Ubuntu One](http://one.ubuntu.com) would be nice. They're [using propietary but open protocol](https://wiki.ubuntu.com/UbuntuOne/TechnicalDetails#ubuntuone-storageprotocol) based on [Google Protocol Buffers](http://code.google.com/p/protobuf/). There's [protobuf for Haskell](http://code.google.com/p/protobuf-haskell/) so it should be possible to compile [the protocol file](http://bazaar.launchpad.net/~ubuntuone-control-tower/ubuntuone-storage-protocol/trunk/view/head:/ubuntuone/storageprotocol/protocol.proto) to Haskell code and then use that to implement the native Ubuntu special remote.
