No, not at this moment. I tried a fifo, but that won't work due to
O_EXCL and O_CREATE the rbd command uses.
I think it should be possible to export to stdout, but it will require
some code changes.
I created a feature request for it: http://tracker.newdream.net/issues/3380

I thought we should extend 'qemu-img', adding import/export there? That
way it would work for all qemu storage drivers?

seem to be already possible:

"qemu-img convert -f qcow2 -O rbd /data/debian_lenny_amd64_small.qcow2 rbd:data/lenny"
