Why not just skip the abstraction layer and interface directly with your offsite backup using unix primitives, and tools like rsync ?
I know there's a provider out there that does this ... on the tip of my tongue ...

Also what I'm after isn't offsite backups but seamless directory syncing (with cloud storage to eliminate the need for peers to be online simultanously), which is related but not exactly the same.
Dropbox, SkyDrive, Google Drive fit this niche generally speaking but Dropbox is the only one that has full coverage across the OSes I use regularly.
The UX is not as nice as Dropbox, but I've been using a free account for about 2 years now and I'm pretty happy with the service and the support (especially given that I'm not a paying customer).
Quirks are that deleted files count towards your quota until you delete them from the list of deleted files (deduplication makes this a bit less painful), and there isn't a way to bulk restore files deleted after a certain time.
