Hi Mungo,
As for Chimera standalone (notifications sent to stdout rather than a REST service), I experimented a bit.  Using the Mac version of Chimera, I opened a structure and changed selections after using the command:  listen start selection

(A) when I started Chimera by clicking the icon, I’m not sure where the notifications went (I didn’t know where to look for stdout)

(B) when I started Chimera from the Terminal prompt as per <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/startup.html>, I could see the notifications in that same Terminal window.  For example:

[chopin:~] meng% /Applications/Chimera1.10.1.app/Contents/MacOS/chimera
SelectionChanged: selection changed
SelectionChanged: selection changed

Thus it is working at some level, although a more complete answer regarding notifications to a REST service may not be forthcoming until our expert on this topic returns to work in a couple of days.
