We could do it in two steps. You could set up nova-compute -> Glance -> nova-objectstore (testing purposes only). This would allow us to remove the S3 code from Nova, but people could still use nova-objectstore if they don't want to set up Swift.
Incidentally, it's also possible for Glance to use a local filesystem rather than a remote store at all. This is perfectly reasonable for small setups.

Subject: [Openstack] Deprecating nova-objectstore
The objectstore in nova is still alive in Bexar. The long term plan
seems to be to get rid of it: it's still using eventlet and Glance is
now covering most of its featureset.
It is probably too late to remove it for Bexar, but we need to have a
plan for Cactus. IIUC the objectstore still provides an easy way to do
EC2-style image upload/registration.
To do it with Glance, AFAICT you need to use an S3 backend (Swift with
the S3 frontend or Amazon's S3 itself). That sounds a bit overkill, so
does that mean we need a basic "S3-like service" to cover for that use
case ? Should it be provided by Glance and reuse Glance filesystem
backend, or be done outside Glance and reuse the S3 backend ?
