This is an option. This post and thread are the public side of
conversations I'm having with both RH and SAS. I'm intersted in guaging
interest if only specific Linux distributions/configurations are
supported. A specific suggestion is that SAS would ship bundled with
the supported Linux configuration.

Making Motif a requirement was more or less what I was trying to say. I
think this would be an acceptable system requirement. We're talking
about people/organizations with a software budget, who happen to

I think this is a showstopper. I'd like more information on the current
situation and/or development status.

It would be appreciated ;-)

As I said, I'm in contact with people at Redhat -- playing matchmaker,
if you will. This is geographically relatively convienient -- RH and
SAS are neighbors, in Durham and Cary, NC, respectively.
