One thing I like is seeing people do some good work out on the field. Kevin Sullivan is a TSP over in the states and has done a really nice live meeting for the education sector! However it can be applied to many other business sectors in the field.

Check Kevin's demo presentation and demo. Its around 57 Mins long!

I think I need to kick myself and get doing live meetings for you folk! And see how we can get some video on this blog for you all to sit back and watch!
