My very humble opinion is that the Beagle board (or equivalent) would be the
the
best solution. I like the idea of a processor dedicated to EMC2 that could be
built in to the machine control box with a remote GUI that could run on a
number
of various platforms (perhaps even a smartphone?). I believe Jon's intent was
to
have the GUI talk to the Beagle via Ethernet. All we need now is for that
German fellow to complete the RT kernel!

Off the top of my head, the parts of EMC2 are sort of like this:
(Sorry, the ASCII art is too convenient)
EMC2 Start
(G-code interpreter)
|
(AXIS User Interface)
|
(Task Scheduler)
|
(Realtime Motion)
|
(Realtime and User I/O)
EMC2 End
My guess is that Smooth stepper with EMC2 (and Mach) would be like this:
EMC2 Start
(G-code interpreter)
|
(AXIS User Interface)
|
(Task Scheduler)
| EMC2 End
* USB *
|
[Smooth Stepper--(Realtime Motion)--(Realtime and User I/O)]
I believe Jon's work with Beagle is similar except EMC2 would also be on
the Beagle.
