 It seems like this kind of exploit is dying out, particularly as
different flavors of Linux proliferate, each with their own slightly
different libc and userland; in the Windows world, however, we still
find "universal" exploits that work on NT4/2k/XP over a variety of
service packs.

Doesn't this implicitly support Dan Geer et al's argument about
software monoculture?

In fact, wouldn't the "linux monoculture" concept constitute a bit
of a misnomer?  Each "slightly different" userland and libc would constitute
a different flavor, right?

Nevertheless, the received wisdom remains that "If linux took over from
Windows tomorrow, all the hackers would concentrate on linux flaws, and
we'd be in the same position."

You are also forgetting ASLR as it is getting deployed in most new 
Linux systems. This reduces the mono culture aspect.

(Windows is catching up here too.)

Ciao, Marcus
