Thanks again, Ciaran, and everyone else. I'm now in a more ambiguous situation where someone else (see email below) wants to distribute a compiled/binary image of my program along with his free-but-not-open-source program. My only concern is that he not make a profit without also making some sort of commensurate contribution to the open source community. Here's the email I need to reply to (hoping the breach of netiquette is mitigated by the public purpose)... "I am developing PocketCAS, a free Computer Algebra System for Windows Mobile devices. For this purpose, I have compiled MimeTeX for Windows Mobile, using cegcc (http://cegcc.sf.net). PocketCAS uses the output of xcas (http://www-fourier.ujf-grenoble.fr/~parisse/giac.html) and then sends it to MimeTeX to get beautiful TeX graphics. I would like to distribute the precompiled MimeTeX executable alongside PocketCAS with a combined installer. PocketCAS will be free of charge for non-commercial use, but I won't release my source code under the GPL. "I hereby ask for your permission to distribute MimeTeX in the way specified and I would like to ask you under which version of the GPL MimeTeX is released, so that I can provide the correct version of the GPL alongside MimeTeX. Best Regards Daniel Alm <[EMAIL PROTECTED]> I'm inclined to say, "Go ahead and distribute a binary image of mimetex along with your PocketCAS." Is there any open-source-related reason (or any other reason) I shouldn't say that? Should I maybe instead say something like, "Permission is granted to distribute mimetex with free versions of PocketCAS, but not with commercial versions."? I couldn't google any info about pocketcas or about this daniel alm (there's an artist with the same name). What kind of issues are involved in these kinds of situations? Do people more often say "yes" or "no", or is it too complicated for a standard reply?
