Hi, Andrew.
Right, I didn't realize this. I read the GPL FAQ link Martin Konrad
referenced in his reply which confirms this. The FAQ entry does say,
though, that the person or company to whom you give the source code is
free to publish it, so I wouldn't base my business on keeping the source
code private for this case.

To me, that supports what I said.
