I agree with you about Gentoo but I'm not totally reassured about my=20 distro. Let me explain the problem The GPL doesn't say much about binary distribution. Here is the whole=20 thing: > 3.

Now my little distro always does a) If you buy CDs, you get the source=20= CDs bundled with the the binary CDs. If you go to their web site, the=20 source ISOs are next to the binary ISOs. I could do a) myself but I=20 would have to double the number of CDs I burn. I cannot as a practical matter do b). I may never see some of these=20 people again. Doing c) is, I think, what you had in mind when you talk about the=20 software being available "via the same source that we got it". The=20 problem is that my right to do c) is contingent on my distributer doing=20= b). But my distributer didn't do b), he did a). By the plain language=20 of the GPL, I can't point back to "the same source that we got it"=20 without "a written offer valid for at least three years." I have no=20 such document. You make a good point about vanilla source. I think it provides a way=20 out. As individuals we might have a hard time promising to provide=20 source code for three years but PLUG could certainly do it for us. I=20 think a statement on the forms saying something along the lines of: 'Many of the programs you received today are Free Software. You have=20 the right to review the source code for at least the next three years.=20= Visit the PLUG website at http://plug.phoenix.az.us/ for pointers to=20 where you may download the source code.' Would satisfy both the spirit and the letter of the GPL. I realize I'm being nit-picky but these are litigious times.=
