I was thinking about the 'maplink' part of the edit form, if
OpenGuides can create/get lat/long coords then couldn't it
automatically build a map link?
Multimap links are of the form:
So all OpenGuides would have to do is glue the numbers into a string,
Also, from a usability point of view it might be nice to have the
'find within distance' form as a set of links, it's only a small set
of options so it could be a nice wee button arrangement beneath a node
title or something - one click instead of two and a half.
