Is this limitation one that the comedi author(s) feel is justified 
given the boards out there?  I.E. is it a rare situation when the 
board(s) installed in a machine could readily support multiple asynch. 
IO on multiple subdevices (esp. in realtime) without stepping on each 
other's toes?  In other words, would it be terribly hard for someone to 
come along some time in the future and modify the comedi internals to 
support multiple input commands on multiple subdevices?  Or would it 
create a buggy and horribly messy situation due to the way the boards 
themselves are designed?
