This is what i found about parrot...pretty much like .NET runtime?
Parrot--the language-independent interpreter engine that will execute code written in the new Perl 6 language. Designed to be language independent, Parrot can be used to interpret other dynamic languages such as Python, Tcl, Ruby, and even Java.
I just went and reread that stuff, Jim, and man, is that dry as a bone. Except for the comparison between Larry and Guido's decommenter programs and the part about Matz and Ruby, that just sounds so serious. Given how much of Perl is changing for Perl 6, it sounded so plausible at the time that I had a hard time believing it was supposed to be a joke!
