There's a critical difference here. The GPL can accompany the reference card. The invariant material must be in the reference card. I explained months ago, and again last week, why this is not so. A similar issue has come up recently on -devel[2] regarding single files downloaded out of a tarball or a cvs repository. Hopefully it's clear that making the license available by reference is sufficient to allow people to download single files from a cvs repository. "Making the license available by reference" does not satisfy the GPL. The GPL must accompany the GPL-covered materials. Access to the program as a collection of files, in such a way that the user might copy just part, is acceptable as long as you do not encourage people to copy less than the whole that includes the GPL.
