Anyone tried Bitcasa storage service on their Surface RT?

You may have saw the Verge article yesterday about this service coming out of beta & open to everyone now. They have apps for most platforms & have one in the Windows app store. Apparently its supposed to act as a local drive (but its really in the cloud) & you can add/dowload files to it, view photos, etc like its just another attached local drive.

I have it for Mac (and it performs as advertised) but was wondering how it works exactly on a Surface RT. I'd like to put my entire photo library on it & just use a Surface full time. Thanks!
