Well if you are committed to the Net switch, I think you are committed to the Leightronix (most cost effective). If you were not as concerned about the Net switch and considered another router, you would open up a larger world. At minimum, the best bang for your buck in terms of automation (in this type of budget realm) is the TightRope Media Systems Cablecast (http://www.trms.com). I've recommended and consulted on these type of systems and they provide a great value for your dollar.
In terms of servers, you need to look at the Princeton servers, TightRope servers, and even 360 Systems. Are you thinking SD or HD?
