I wish they would also test the hotel networks in advance and report
to all of us the limitations we?re likely to encounter. And, of
course, it would be pretty easy for a volunteer group of IETFers to
organize a reporting effort too.
There are some commercial efforts appearing in this space, also.
http://www.hotelwifitest.com/ is a crowdsourced effort that addresses
speed tests, but not port filtering tests.
I would love to see Netalyzer[1] reports from each of the IETF hotels,
including overflow hotels, but that might require more effort or room
nights than the site survey and advance teams normally allow for.
Crowdsourcing might be the way to go.
