There is no Internet in the conference center !! Well. there is connection in only in one room, but that is 56K! To have a computer engineering conference without Wi-Fi is unbelievable and unacceptable. Outside that room, you have to buy Wi-Fi access for $10 per day. $10 for 56K is a ridiculous proposition.
I planned to have a live feedback session for my OOPSLA tutorial, but nobody responded. It is reasonable to expect that the attendees would only give feedback when the tutorial is fresh in their mind, i.e. when they are attending the tutorial. But who would pay $10 to do that? So, no feedback for you !!
