He could download my shutter widget, then start his work based on that.
Does he already have a configuration file with his raw code in it?
Then just add that config file to his lirc config and extend shutter for his device - not much work indeed.
Or even simpler, abuse one of the existing remote configs coming with shutter (they are in /opt/tomch.com/shutter). He must just rename my original file for the cam he sure doesn't need, then insert his own config file and rename it to the same remote and command names that I use.
