There are people who sell things like the application under question. So whether or not it is for public sale, the concerns of publically selling it are not irrelevant for applications like that.
Furthermore even if it is private, as a developer Scott may face IS barriers if he wants to modify current network policy and use Citrix. Again, if they have Citrix, it isn't an issue. If not, then it could be.
Which is, of course, irrelevant since he delivered through HTTP. :-)
