Yep, we're planning to add support to DeviceKit-disks for exposing the
(privileged) operations that btrfs may expose (locked down by polkit,
etc etc). There are also plans to expose these operations in the UI in
Palimpsest and/or Nautilus. I don't think snapshots is going to have any
Palimpsest UI (it belongs in Nautilus I think) but the multi-disk stuff
definitely will.
As always, DKD and Palimpsest is supposed to be complementary to the
command-line tools. So all this is only relevant for creating nice UIs
for managing btrfs.
(Btw there's still some work needed in udev/blkid (but hopefully not in
the btrfs on-disk format) to properly export everything we need - e.g.
things like number of block devices in the multi-disk filesystem, maybe
the "raid" level and so on. I haven't gotten around to looking at this
in detail yet. It's on my TODO list though.)

People hacking on Nautilus will have to look into this with both ZFS,
btrfs and possibly other filesystems in mind. I haven't seen anyone do
work like this and it's not trivial.
(Oh, and if it turns out that creating/destroying btrfs snaphots isn't a
privileged operation (I can't remember at this point) it would probably
make sense for Nautilus to just use the btrfs tools directly instead of
going through a system daemon. There's just no need to overcomplicate
things.)
