Its available (almost).  The current  talk about an unstable CVS is 
about how we're going to release it.

I have all the "relate()"-related function (like overlaps(), 
within()...) and isValid() working.  There's about 1000 test cases and 
they all pass.  This code is based on GEOS (geos.refractions.net), which 
is based on JTS (http://www.vividsolutions.com/jts/jtshome.htm).
The only issues remaining are a few bugs in GEOS regarding memory 
management, and ensuring the build process is working.

An experimental release will be comming out this week, and we hope a 
more stable release (including a new GEOS) a week or so later.
