[OS:N:] Another question about Licenses

["Anthony Saffer" <anthony safferconsulting com>]

>From the answers to my original post surrounding the GPL and its application
I am beginning to wonder if the GPL is indeed the license I need for my
software.

Basically, what I am wanting to do is this: I am working on a tool that will
be of use to software developers. I want to sell this product but include
the source code in each package sold. This way, companies will be able to
change things to suit their needs. However, I want to maintain a fairly
tight control over the source so I want to license it in such a way that
they cannot turn around and resell it or give it away themselves (even
modified versions). I also want all revisions that they make to be
resubmitted to me so that I can decide to include it in a future release or
not (or I am seriously thinking about just distributing the mods for free to
customers), Knowing all of this, is the GPL still right for me? If not, what
would you suggest?

I want it to remain "open source" in that everyone gets a copy of the source
when they purchase it. But I want to maintain control so that I can protect
the integrity of the software.

Thanks,
Anthony
