I might be a bit wrong here, esp. with BSD. :P Mea cupla.

I know that BSD, unlike GPL, does not require that derived code be BSD licenced. And when I was talking about "source code" I was thinking of the original code (not the derived work), but I was wrong about BSD not requiring that you provide the source. Many big users of BSD code (e.g. Apple) provide the BSD source code they use, so I thought it was required.

However, for GPL, "commerical" vs. "noncommercial" is irrelevant.
