Putting aside the whole actual core subject material...

I find it bizarre to do a remote video attendance to an in-person meeting like that. I hate it when they plan that sort of thing at work. Whenever I am part of that sort of planning, I try to make a 'remote half' either before or after the event and an 'in person half'. It's just seems disrepectful to make a whole bunch of people travel and then waste some of that time listening to a person speak remotely that they could have listened to anywhere.
