I think storing it in a pixmap on the server and sending back a
pointer to it is an excellent idea.  It should also help with
debugging and testing.

An alternative would be to have some sort of callback scheme, but then
you'd run into trouble with various tunneling and firewalling schemes,
so a server-centered approach makes more sense.
