You can modify GPL software for private use. That clause only kicks in
when you "distribute or publish" the work, so you're generally OK if
you're just using it within a single company. Maybe that's what Huib
meant by "closed source".
"distribute or publish" covers wen you put your additions for download, or
otherwise gives away copies.
You can do any additions, keep it on your own servers, and sell the
result to clients.
