I just had Rob Moodey from Matrox in to demonstrate the new Matrox Veos system:

This system works a little like a dual/triple head to go but can extend DVI to 100m down coax. Even though the units I had were prototypes, it worked with Catalyst straight out of the box. I was able to send two 1280 x 1024 feeds 100m in our warehouse. Worked first time with a Mac. Veos doesn't like our standard def coax. It likes the 4.5Ghz Coax we use with our Lighthouse LED walls.

The units are still in development, so there's still some room for improvement, but I was pretty impressed with these units. If you, like me, have ended up being stitched up on a gig or three with Thinklogical fibre-optic boxes (aka Stinklogical) these units will come as a bit of a relief.
