Thanks, the first one is close-ish, but what I want to do is allow
users to propose a route through existing roads -- like the "draw line
along roads" tool in "my maps" in google...so basically dynamically
routing when you click a new point (or hover, depending on routing
speed). I've looked at the openlayers stuff and it looks really nice.

The missing piece would be dynamically producing a new (or replace
some of an) overlay by asking a routing server. I am wondering if
anyone has done this. The closest I've found is:


...which is really pretty close.
