Which DUAL Licence should I choose.

[Thomas Schneider]

Hello John, many thanks for your reply :-)  I do *NOT* understand the 
implications of your last paragraph, however.

I would like to OPEN SOURCE the code for maintenance (by other's) , and 
would *at the same time* like
to *earn money* out of it.  I did invest more than 8 man-year's into PP, 
the  Program Porting machine,
and would like, as the Author, to get some payback for it's usage.

As far as I understand it currently, this is NOT POSSIBLE with the OPEN 
SOURCE Scheme at all.

When you could explain the implications of your last sentence (marked 
below), you will be more than welcome!

Thomas Schneider.

Quote: ... without any need for anything but an open source licence of 
the code itself.

This paragraph I don't understand!.

I do have some partner's around the world who might be interested to 
CONTRIBUTE
to my software. In order to be able to do so, I would like to OPEN 
SOURCE the Software on KENAI,
but SELL it !

As far as I can see it now, this is a *contradiction* per se. Isn't it ??

Thomas.
