I think it's fine.

That depends on the size and frame rate of your "large" video screens. Full
HD at 24 fps and 24-bits color depth is already 1.2 Gbit/s before protocol
overhead. Support for raw video streaming (over RTP) could be added with a
reasonable amount of work, but I am not fully convinced that GigE is fast
enough, or that it won't hit other bottlenecks, such memory copying speed,
socket buffers size, checksumming (unless the NICs can offload), or
