'Ocean' is a very interesting, and probably proper analogy. 

Since you are using all IIgs's, then I'd have to say, not really, no. 
Timing shouldn't be a problem since the parallel card will control 
any issues that would arise. 

Here's a funny irony for you. I actually, in the 80's, ran NC lathes 
which were controlled by Apple IIe. Of course there were dozens 
of other boards and devices in the box with it, but that was for the 
most part the main controller. 

Anyway, what you're doing can be done, and sounds like it will be 
a lot of fun. So, good luck, and if you need help, you know where 
to find us.  <[8>D
