I have done this is Javascript, but we need to be able to do it server
side and generate the *exact* same URLs.  Lars is correct that the float
precision and print format will matter here.  A quick attempt I made to do
the same thing in Java generated different URLs, and Steve's applet tiling
scheme is different to the javascript one so they can't share tile cache
even if we move GPS track drawing to the applet.

boundaries? Almost every WMS map server take this as url parameter (in
fact, OSM seems to be the only I've seen using something like

Yes.  The problem is, for a given lat/long (the location of a recent
edit), what are the *exact* URLs of all the tiles that need refreshing?

Tom.
