The coordinate limits of the 3D engine are the biggest issue. r100/r200 radeons for instance have a coordinate limit of 2048x2048, so the largest surface you could successfuly render to would be limted by that. Also, if you are not using X, you'll have to add support for multiple crtcs to either the fbdev driver for your card, or the write a new driver that provides similar functionality. For multi-card 3D rendering you might want to take a look at dmx/glxproxy and chromium. These provide methods for breaking down the rendering and sending it to multiple hosts.
