Good point, but if you want to do reasonable monitoring, don't you also
want information on CPU, disk, etc.? So really, you need shell access
anyway. Plus, my point was the the version output isn't all that
reliable anyway, because it tells you about the build system and build
compiler, not the host system and host compiler (if any). I think it's
tempting but not terribly practical.

That was one reason why people approached me to raise this subject. But
after consideration, I think it is much better to actually query the
maximum values directly rather than trying to reverse engineer them from
platform information.
