Get yourself a router and lan cards and cables for each computer. Create new shares on each computer to set your network up, then find a Netrender plug for Maya. Dirk Balliach (sp?) has one at his site. Anorther one to check out is Muster from Virtual Vertex. You can d/l and use it between two computers as is, but need to register it for any more. I wanted to try the Net Render plug from Dirk Balliach but wasn't networked at the time so I couldn't test it. You have to have Maya installed on each computer as well so this is where a floating license is better than a node-locked license. Good luck

Red bellows of flame have blackened my stones
Convulsing my frame and cracking my bones
Hell's dragons of steel who roar in their chains
Crawl into my caves to suck out my veins.....
