Hi again Dave,

That's a really good question.  I ran FreeView today for some visualization tasks and Gaucamole averaged about 85 KB/s.  Keep in mind that I was making a point to be fairly active during my test -- if your workshop is anything like those I've seen, there will be significant downtime while some participants pause with questions and others rush ahead and then have to wait.

Do let me know if I can help in any way with an assessment of the venue.
