At a press conference on blue-cat, an employee of Lynx told me,
that Bluecat-Linux is GPLed. At least, Bluecat-Linux is only a
non-realtime target-OS, that should be 100% compatible with
LynxOS 4.0 (better read it the other way round). So you don't have
to pay any license fees for selfmade additional copies/installations
on hundreds of targets.
But what is sold (from what i have understood) is the
integrated realtime development environement, that is
running on top of a RedHat-based distribution. As
this tools are user-space programs (like StarOffice, etc.)
developed by Lynx, they don't fall under the GPL.
As Bluecat-Linux is also RedHat-based, you can use Bluecat-Linux
as OS for the development system, as well, of course.
You may use Bluecat-Linux without the LynxOS-Tools, for
example as a base for RT-Linux applications, and you
will also get support from Lynx if you need it, but that
will be not free of charge, of course. I asked exactly
that situation. The answer was: "As long as one
of our product (including Bluecat-linux) is involved in any
development, we will give you commercial support".
That follows the basic idea: software is free of charge, make money with
support.

Ok, it would be nice to have the IDE also free of charge, but
in my opinion $2000 are really peanuts, compared to other
industrial IDEs. IMHO, those, who can't afford that, will not need it!
emacs, gcc & co. are quite ok for doing good development up to a
specific point, i.e. the full flight simulator worth $12.000.000
running on linux described in the linux journal half a year ago,
was completly developed with linux and gnu-tools.
If you have a bigger project than that, so that you need such tools
like Lynx offers them, then woun't look at the $2000 - trust me :-)
just my 0.02 euro
