One thought I had, is that it would be very nice to break up the -drive 
file=foo.img,if=scsi syntax within the config file.  In general, I'm 
thinking something like:

[drive]
file=foo.img
if=scsi

or:

drive {
   file=foo.img
   if=scsi
}

or even:

drive:
   file=foo.img
   if=scsi

Basically, I'm looking for a syntax for sub-options.  This would be 
useful for -drive or -net but I also think would lay the foundations for 
specifying a full machine config.

It would get very unwieldy on the command line to have a large number of 
suboptions but it works reasonably well within a config.
