Any good reason why you remove the list of propierties?

What I want to do, to make usb modular I need two things:

a- a way to defino an alias, that "mouse" is equivalent to "QEMU USB
   Keyboard".  One is the qdev name and the other is the name passed to
   --usbdevice name.

b- things like disk are composed of:
   "disk" : "rest of disk arguments"

   My plan was to add both of them as properties or similar.  Any better
   idea?  I can put it in one struct or similar, but it is not trivial
   to find where to put things really, because the "mouse" part is
   filled in usb-hid.c or equivalent, and the "disk" arguments part is
   filled in vl.c

Later, Juan.
