It is worthwhile, when designing virtio, to keep in mind as many possible users as possible. In addition to block and net, I see at least the following:

- vmgl (paravirtualized 3D graphics) [http://www.cs.toronto.edu/~andreslc/xen-gl/]
- scsi (for tape, cd writer, etc.)
- framebuffer (with just one request to share the framebuffer?)

There are probably more.  Any ideas?

- Fast inter-domain networking, a-la XenSocket.

Yup.

- PCI (or your favorite HW bus) passthrough, for your favorite oddball
  device (e.g., crypto-accelerators).

Won't all high-bandwidth traffic be through dma, bypassing virtio?
