My second post on multicast events is now up, and here’s a video showing the basics.<\/p>\n

It was also an excuse to get to grips with the video capturing software – CamStudio<\/a> – (and technique!), which proved to be a frustrating exercise to say the least, but I am quite pleased with the eventual results and plan to do more in the future.<\/p>\n
