Despite my recent post about Ruby on Rails I'm pleased to announce that the first beta of Ruby.NET from my research lab. I'll let the release speak for itself:

We are pleased to announce the preliminary Beta release of the Gardens
Point Ruby.NET compiler. Note: this is not just a Ruby/.NET bridge, nor
a Ruby Interpreter implemented on .NET, but a true .NET compiler. The
compiler can be used to statically compile a Ruby source file into a
verifiable .NET v2.0 assembly or it can be used to directly execute a
Ruby source file (compile, load and execute). Our implementation is not
yet fully complete, but it is the only Ruby compiler that we know of for
either the .NET or JVM platforms that is able to pass all 871 tests in
the samples/test.rb installation test suite of Ruby 1.8.2.

Looking good. I haven't been involved in the actual development but I've been kept up to date with internal presentations and discussion and I'm currently looking after the website so I was involved in getting the release up this morning... but don't blame me if we get slashdotted.
