Yes, we've been thinking along similar lines here too.  At the end of November
I put in modelling for the "Console" class, which is where we intended to put
these options, and like you say, the modelling is very similar to the VBD and
VIF handling.  We've added a protocol field, which allows you to choose VNC
versus SDL, but that's all that's gone in at the moment.

This doesn't work at the moment, because it hasn't been implemented in Xend
yet.  The intention is to add settings for all those fields that you mention
above, and of course implement the Xend-side stuff.  It's on our list
(somewhere behind the networking stuff and the asynchronous task handling).

Ewan.
