Hi,
Actually, there is already a channel to pass pointers to qdev devices: the pointer property hack. I'm not sure we should contribute to its user base or take the chance for a cleanup, but we are not alone with this requirement. Point below remains valid, though.
It is considered bad/hackish style as you can't create that kind of devices using the -device command line switch (or from a machine description config file some day in the future). So we should not add more uses of this, especially not in patches which are supposed to cleanup things ;)
cheers, Gerd
