At ther very minimum I would expect some new policies to be put in place on what you can have when you camp out but I would not be surprised if it's more than that. Any type of item that could be a fire hazard such as heaters and generators are likely going to be banned. The university is really fortunate no one got hurt and the fire was contained and put out quickly because being it happened on university property and they allowed the situation that led to it so there likely would have been some liability issues to deal with if something bad had happened.
I know the students will hate this idea but the most practical thing to do would go to a lottery or merit type of system to claim assigned seating for at least the KU game. Today's students have the luxury of first come first serve for every game but it was not always like this. Not sure which year exactly it went to that but I know at least through 2000 you only got 4 lower level games based off of what number your season ticket claim was and the rest you had to do general admisission upper level seating. In the fall you went to the ticket office on the days that your number range was allowed to and pick out a 4 game package for your lower level seats. If Iowa was playing at ISU that year you had to choose between a package with either KU or Iowa because they were the most popular games and were never in the same package. I don't think going back to that old system is the solution but for at least the KU game having some kind of assigned seating system makes sense. If you really wanted to reward those who showed up to every game then have a merit system based off the ticket scans from previous games, those who attended the most games would get a higher number to pick out assigned seats. Make this an online thing too which would avoid camping out at the ticket ticket office to claim it too. You could say anyone with a number from 1-200 can pick out tickets at 8am then 200-400 at 9am, etc. Back when they did the 4 game packs you had to show up to claim, if you wanted to get tickets in a group then you had to wait to do it when the highest number in your group could go so once again if you have a group that attends every game and you went on a merit system you would still be able to get good seats since you should all have a good number.
Just some thoughts, I think it's probably a forgone conclusion after the tent fire that something will change. No one is questioning the student's spirit and dedication but at some point safety and the university's liability comes into play and find a reasonable way to protect everyone's interests.
