Yeah, that would be cool. When somebody gets the time to work on it
and test the output. :-)

Probably, yes. I looked into live CDs for etch, but had problems. I
should be looking into that again for lenny.

Ooh, now that's a cute idea. :-) I'll add that as a SoC suggested
project right now.

No, we gave up on that quite a while ago.

The netinst is much more likely to be useful longer-term; you have a
minimal but useable base system from the CD, with nothing further
required. If (for example) there has been another point release or d-i
update since your businesscard image was created it may break...

Oh, absolutely. That's one of the biggest changes I made in
debian-cd/mkisofs to improve performance. However... if we want to
continue providing torrent downloads (which are very popular, I
understand) then we do still need to make the full images too.
