Dynamic Reconfigure would help, as it would eliminate the need to 
shutdown nodes and/or rerun the launch file or rosrun command, but it 
still would add an extra step on startup to make sure the cameras 
started correctly.  But then again, it would be less likely to cause 
problems with other camera hardware for an issue that sounds like it is 
relatively obscure(although it sounds like odd behavior from 1394 
cameras is not unheard of).
