Two possibilities here:

1) either the GUI provides the pre-work to launch v.net.path, piping in 
the coordinates

2) someone amends v.net.path so that it accepts coordinates either from 
a file or as parameters.

I think this is typically a module where interactive selection by mouse 
should be possible.
