There's a standalone tool to start/stop jack transport via MIDI/MMC:
http://nedko.arnaudov.name/soft/jackctlmmc-0.tar.gz  - It's hardcoded to
  use the default MMC commands for start/stop/rewind, but can be adapted
easily.

If you use ardour - enable 'generic MIDI' Option (and connect your MIDI
device) - Then hold CTRL-key and press the middle mouse Button on the
play button (this key combo allows to re-assign MIDI bindings).
press the midi-footswitch to assign it to the play btn. - Repeat for the
stop-btn.
  Since ardour 2.1 those midi bindings are saved in
~/ardour2/ardour.bindings - For older versions you'd need to save the
ardour session as a template.


good luck,
robin
