I think this will be very hard. The flash plugin integrates quite deeply
with the browser (for sizeing, positioning, clipping, DOM integration,
etc) and the browser will be running in the guest OS, not on the client.
Furthermore such deep interaction with the client is not suitable to the
spice protocol, because it must handle e.g. the client terminating or
the guest being migrated to another machine. In this model a lot of
important state is being stored in the client and not in the server and
this doesn't nicely handle situations like that.
