This is just a quick announcement about an X-Windows DS2Key server I've written, aptly named xds2key. This allows X-Windows users, particularly Linux/Unix users (though it works with Cygwin/X, as well), to use DS2Key with, well, any application that takes key presses. Currently, it's quite primitive. It has fixed key mappings, it's pure text mode, etc, and really it was written as a proof-of-concept, but it functions, and I don't intend to work on it too much more. If anyone wants to add to it, though, feel free, as it's released to the public domain. Anyway, you can find it here. Basic compiling/running instructions are there, but there's no fancy schmancy configure script or anything. As for requirements, it just needs an X server that supports the XTEST extension... which encompasses any XFree86 or Xorg-derived server. Not sure about others (eg, Solaris).
