A Parrot based Perl6 which runs of 99% of hardware, but is 5 years out
...I'd choose the Haskell/Perl6 solution and leave the worry over the other 9% of hardware to the future. (And I'd venture a guess that it'd be about 1000 times easier to get GHC working on NetBSD/SPARC then to get parrot in usable shape.)
