One of the main things will be focus control. There is such a myriad of cameras and lenses and rods, that controlling focus gets tricky. Stanton makes a great rod bracket system that lets you use the stanton motor on film cameras. You might want to look into a Heden motor and controller, or perhaps go wirelesss with a Preston FIZ ($10,000+?). Zoom control is readily available out there (microforce) but a long cable extension is always elusive. Camera start and stop is also very desirable.

Work a few student films and coordinate with the AC and you should be fine!
