Your post is a little confusing but I'll give it a shot.
[Luis Sierra]"I can down grade to Leopard in order to have that machine on the server."
You don't need to downgrade to have the computer comunicate with a different that is running server.
Most of the new Mac's CANNOT run on anything other then Snow Leopard. ANY Mac that was released after Snow Leopard was released needs Snow Leopard because older versions of the OS will not have the support for the newer hardware.
There are no "technical solutions" to your "artistic problems".
Don't let technology get in the way of your creativity!
