I have used ardour solid for about a year and a half now. I bought the video and Mixbus great combo! I was using it in linux primarily but now on 10.6.x. My setup is a Yamaha M7CL 48 channel console out adat lightpipe to presonus firestudio lightpipe. 32 Channels in and out. Works great doing 24 to 32 track recording at once for live recording. I would like to say congrats on this and put my first purchase in and soon to be more.
I am waiting for a linux version of this for sure.
