Evenly distribute points along a path I have a user defined path which a user has hand drawn - the distance between the points which make up the path is likely to be variant.
I would like to find a set of points along this path which are equally separated.
Any ideas how to do this?

If you measure distance along the path it is no different from a straight line.  If the length is $L$ and you want $n$ points (including the ends) you put a point at one end and every $\frac{L}{n-1}$ along the way.  If you measure distance as straight lines between the points there is no guarantee of a solution, but you could just start with this guess (or something a bit smaller) and "swing a compass" from each point, finding where it cuts the curve (could be more than once-this is problematic), and see how close to the end you wind up.  Then a one-dimensional rootfinder (the parameter is the length of the radius) will do as well as possible.
