the language, to me at least, sounds like you are permitted to do
whatever you'd like with visual itself, as a package/platform.

"It is not permitted to extract the GPC code from the distribution as
the basis for commercial exploitation"

thus, you can't pull the GPC bits out exclusively and use them to
spearhead a commercial product, but that doesn't mean you can't use
visual as a platform in a commercial project.  at least that's how i
understand it.
