Will this start it the first time, that is, at boot?  Is this on 
regular ol OS X, too?

Will GUI be ignored if there is no card or will it break something?

With Windows 2000 I have been able to run Rev-based services with a 
GUI or with the GUI ignored.

How do I make a non-GUI app with Revolution?  I always get a stack 
showing.

Cool!  I'm already splitting mine in two.  I'm using tcp/ip for 
communication.

My admin half is a GUI.  Based on what you are recommending, maybe 
it (or a version) should also run over telnet or terminal.

Wow!  Thanks for all the info, Bill!
