This IS the RoadMatcher tool I've been using for finding standalone ways. 
I have been using the stock roadmatcher plugin in JUMP and OpenJump (I have 
not changed any code in it).

I think I sent that link below when I started looking at it (I think I added 
it to the wiki at some point as well).

I typically have been using these settings for the AutoMatch
Minimum Line Segment Length: 5.0E-7
Standalone Minimum Distance: 5.0E-4
Matched Maximum Distance: 5.0E-4

When all the data has been reprojected to epsg:4326
I suspect these settings could be tuned more.
