Look it up at http://www.gnu.org/copyleft/gpl.html
Excerpt:
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms
of Sections 1 and 2 above provided that you also do one of the
following:
a) Accompany it with the complete corresponding
machine-readable source code, which must be distributed
under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than
your cost of physically performing source distribution, a
complete machine-readable copy of the corresponding source
code, to be distributed under the terms of Sections 1 and 2
above on a medium customarily used for software interchange;
or,
c) Accompany it with the information you received as to the
offer to distribute corresponding source code. (This
alternative is allowed only for noncommercial distribution
and only if you received the program in object code or
executable form with such an offer, in accord with
Subsection b above.)

This looks to me compatible with 3b above.

It would seem to me that a written offer, as per 3b or 3c, must be
supplied with the distribution, so the above two options don't look
kosher to me.
Legal disclaimer: I am not a lawyer, so consult one (or write to GNU
and request clarifications).
