I use Qlab but not as a Media Server. I use it as an automated follow spot caller. Have a read if interested.....

I dont see QLab really cutting into the Catalyst market simply because most people want easy control from the console. Sure, you can fire Midi to QLab but I find most my rentals are to Lighting Designers that are just getting into Media Servers and want a very simple and user friendly solution. Catalyst provides that.

However, I do hope Richard keeps Catalyst up to date and competitive with the other Media Servers on the market.
