The last time I looked at parrot (a couple of months or so ago, so
things may be quite different) parrot was still in very early
development stages (it had no proper memory management system yet, for
example). At this point it is still very unclear whether anyone
outside of perl is interested in what they are doing. The python
folks in particular don't seem very excited about it as far as I can
tell. The parrot folks have also made a number of unusal design
decisions that may or may not pan out in the end. My impression is
that the presentation of their ideas at the Lightweight Languages
Workshop last year at MIT (http://ll1.mit.edu/) was not received with
overwhelming entusiasm by an audience who know something about this
stuff. But who knows, it's still early days.
There is work in progress on compiling R to byte code for a virtual
machine that is specific to and optimized for R (includes things like
opcoded for vectorized arithmetic). Once this is complete it should
be possible to use the R byte code as an intermediate language for
different back endt including portable assembly languages (C, C--,
e.g.), JVM byte code, .NET byte code, or maybe parrot byte code if
that project matures into something interesting.
