800x480 LCD Gui driver

I've been dinking around the lcdproc documentation and the Myth lists 
and documentation looking for a solution that would effectively 
implement LCDProc on a standard X based GUI window. I don't see one that 
matches what I think I want. Has anyone done something like this? I see 
the glcdlib, but that's not what I'm looking for. I don't believe the 
SVGA driver is quite right either. It should be smart enough to handle 
much larger displays with a full complement of capabilities.

If there isn't anything like this, I am already starting to tinker with 
a driver model to do it, but I'm pretty new to Myth and to the LCDProc 
system. I have some ideas, but am not sure what would pass here and what 
wouldn't. My current thinking is the following.

A driver that doesn't implement a graphical frontend, but rather becomes 
a forwarding driver to some GUI system. Something similar to the text 
driver, but with an eye towards a full GUI. My goal is to do the actual 
display either using libmyth, or vanilla Qt (haven't worked that out 
yet, but Qt is the leading contender to make this work faster and be 
more portable). Communication is undecided at this point, but probably 
mqueue's or similar. Does it need to be a two part driver? Looking at 
the documentation on the drivers, I don't see how it would work as a 
single entity, assuming you want to start the GUI window before Myth 
starts. I don't see how a driver could be both Qt and live in the 
lcdproc driver model.

I'm looking for some sort of feedback to give me some direction if 
something like this doesn't exist yet. Or, if it does, how it works, and 
what I need to do.

Thanks
