...except that low end games, multimedia toys and stuff like that
often cover the whole range from 486 or Pentium and up. So, you may
well encounter integer plugins on a 686 machine, and there's nothing
in the binaries that automatically prevent P-II+ float hosts from
loading them.

Yeah - and provided hosts are really required to check the metadata,
the "compatible binaries, incompatible profiles" problem is solved as
well. :-)
