Seems to be based on OpenStack [1] Storage [2].
That means any client that supports OpenStack (and Rackspace Cloud Files [3], for that matter) like Cyberduck [4] and a lot more should already be compatible with hubiC.
Do you know a good client for Linux? Their official client [1] requires mono and I don't want to install that on my server (or even my desktop, for that matter).
They seem to use custom OAuth-based facade, so bare OpenStack clients won't work out of the box (or I'm missing something, I'm just starting to read about what Swift is).
First I tried to use API console to get storage API URI and auth token, but I misunderstood something and it didn't work for me.
