Hi, Also, it's not the first time people will be prevented from attending an IETF meeting due to visa issues. The problem has been around for years, and we discuss it whenever there is a meeting in US. Very likely there will be people from "non-banned" countries that won't be able to attend the Chicago meeting because of visa issues - perhaps even more people than those from "banned" countries that won't be able to attend...

And while I agree that some conditions would warrant cancelation of a contract, exactly how would that contract be written that would be acceptable to all parties that would allow for cancelation because a peaceful transition of power brought policies that you don't like. The percentage of likely participants that will be effected? What would that percentage be? Would the inconvenience of implementing Brexit result in a cancelation trigger? One way to avoid liability for individual cancelation expenses is to warn everyone to purchase their own insurance OR not commit well in advance. In the end, no matter where the IETF schedules a meeting a year or more in advance, there might be an issue resulting in cancelation. A major earth quake or hurricane could make the venue impossible. As could the political situation though the litmus test would be harder. Providing first class remote paricipation from several locations worldwide would be awesome AND expensive. Would folks be willing to pay the same registration fee to use such facilities as attending? I worked for a company with such facilities so I know it is possible. David Morris
