so folk have some data to consider, as of tuesday about 08:00 gmt we had seen the following unique associations (ietf-hotel excluded, as is not a measure of choice) 1380 ietf 967 ietf-legacy99 611 eduroam 226 ietf-2.4ONLY 166 ietf-nat64 62 ietf-v6ONLY of course, a device could have been a serial associator, using more than one network over the measured time period. some suggested that the high count for legacy99 is partially due to some devices automatically associating with unprotected networks. i am not aware of a record of any later snapshot if one was recorded. and we can not do further analyses now because we wipe all logs at the end of the meeting just before backing them up (think PII). randy
