I've been to far too many 'tech' events and conventions that the WiFi just falls over and dies. U-Mass Boston was completely unable to handle even the 500 geeks at Podcamp. MIT's infrastructure has been able to handle everything that I've been to there (ROFLCon, Barcamp, etc). Seems to vary massively by venue.
