The FSF can't have a /legal/ problem with it because the GPL permits
You can't distribute GPLed code without making its source available.
That includes limited releases to your friends or a beta test group
or anything else. It would be interesting however if the diffs from
the public version were distributed alone - while it's against the
spirit of the GPL and likely that diffs are a legally derived work
under copyright, I don't know of a court case proving it one way or
another (however, IANAL).

Absolutely, I was speaking in general reality terms. Most Linux users
I know download software in source form and build it themselves
rather than rpms.

Precisely. If you see Linus' comments on kernel modules and the long
debate about whether a kernel module is a derived work or not, it's
clear that an ABI boundary is considered a derivability boundary. I
myself feel that a GPLed DLL can be used by a commercial program
without problem - however while this gets members of the GPL cult
very riled, I have not met one who can point to any definitive test
case history supporting that analysis. OTOH, I can't point to any
either - it's yet to be decided.
: Some of you may find this term offensive. If you do, as per
Ciaran's past request, don't reply to the group when telling me how
wrong I am.
