David Lancashire’s wonderful Adso — which I tend to use primarily for conversions into Pinyin (under Style, select Pinyin) but which can handle much, much more — is now available for download as a Unix binary. A Windows version is expected soon.
This is fully-featured non-crippleware and should run on most modern linux distributions. To my knowledge, it is also the first reasonably-functional and freely-downloadable machine translation and NLP engine in the world.
If I were even half the programmer I ought to be, I’d snap this up in an instant.
