I have a bad feeling you're going a proprietary software route here with this, since you're using VB.
However, I recommend that you find a way to package the box nicely, and become a seller on Amazon.com.
If you want to make it open source,
but make it LGPL so people don't mess with it as easy, you can publish it a lot of places, including SourceForge, Launchpad, BerilOS, or other places that I can't name right off hand.
Hope all this helps.
