The Parrot project has interesting possibilities. Parrot is a virtual machine specification like java and .Net bytecode to be used for Perl6. Parrot's difference is that it is being designed to implement any language. Java's bytecode has difficulties with untyped objects which makes a Ruby implementation difficult. .Net's bytecode is more robust, but still has issues. The designers of Parrot are testing different langauges like Forth to make sure the language has all the operators needed to support most known languages.

An interesting possibility is to have browsers interpret Parrot code so we can write any language and have it interpreted by the browser instead of just javascript.

Now if we could just get an open source spec for denser DVDs and bypass the whole HD-DVD and Blu-Ray war.
