Dave, just a coupla things from the top of my head.

1. Connecting 3 DV streams on one bus is probably un-possible with 
firewire.
I seem to recall an Apple article...
..yep...here:
  http://developer.apple.com/qa/qa2004/qa1365.html

2. The actual DV control protocol (to control the DV camera or any DV 
device)
should be a standard. Sorry to say I'm not knowledgeable about the linux
iee1394 api's or DV libraries.
Doing that research is probably your first task before deciding on the 
platform
(As a sidenote, Apple has this in Quicktime, and you can make your 
custom camera
control/video recording app in Cocoa fairly easily... but only for one 
DV stream at a time..)

3. Is there any reason you can't just tape what you want and then 
transfer the footage
from each camera to the laptop in succession and edit it there ?

Good luck ;-)
