Robert is correct.  I also asked about GOTS (Government Off
The Shelf).  Lot's of GOTS software is available "free" to
those who qualify.  A lot of it wasn't cheap to produce.

We are currently using (and integrating some into our products)
Samba, R, emacs, Tcl/Tk, perl, and other GPL'd and open source
products.

(On a personal note, I've recently decided to release TASH, an
Ada binding to Tcl/Tk [http://tash.calspan.com] under the GPL.)

I wish a lot of success to ACT, Scriptics, Redhat, and others
who are pioneering business models based on open source products.
Even though our product is not and never will be public open
source, I am trying to convince our management that our customers
need and want source code.  I believe this will build their
confidence in our product and give them a level of ownership
that enhances the product.  If it doesn't, we need to improve our
code, not hide it.
