Interesting, Paul. Have you (or anyone else on ag-tech) any 
experience of putting this into an existing lecture room that already 
has standard mic and speakers used for lectures, as well as a PC?

Context is our planned rollout of several insors personal nodes in 
locations that may include existing lecture/seminar rooms. Buying a 
separate echo-cancelling microphone is an option but it sort-of feels 
messy if an audio system is already in there, and securing it may 
also be a problem. Any advice welcome.

How about fixing an AG meeting sometime to discuss this between 
anyone who is interested? It seems to have sparked a lot of interest 
on ag-tech and we might as well use the technology to share ideas and 
experience, after all.
