Yes. I'm sorry. I was thinking further about my comment all night. I
realized that you and Free are working very hard at providing those
kernels and anything that can make your lives easier will be a good
thing.
Looking forward 6 months to a year from now, I realize it will make my
life much easier as I begin to deploy and maintain at least 30 and
possibly as many as 100+ linux based broadcast workstations.
Again, sorry for saying that. Lost my head there.
Lee, your efforts are very much appreciated, too.
