Yes - LWGEOM has had a "beta" release.  For more info, see the postgis 
developers list.  If you get the CVS version, you should see a "lwgeom/" 
directory.  Read the README in there.

The underlying geometry format has changed, but there is a spiffy API to go 
along with it.  

Unfortunately, there's almost no examples of using this code - the WKT/WKB 
parser and unparser are very much separated from the API.

The lwgeom.h file explains the API.
