There's no such hardware restriction, and never really has been 
AFAIK. Even back when PS2 (and older) keyboards were in use, there 
wasn't (to my knowledge) any fundamental restriction that would have 
prevented multiple interfaces being supported. Now it's all USB it's 
moot anyway - you can add something like 60 keyboards and mice (limit 
is 127 devices total IIRC).
The real problem is, as you say, in software/OS support to route 
devices to VMs.
