Please count me in.
There is an AA group that has been doing this (i.e creating an iPass account for frequent flyer use) successfully for the last year or so, but it will soon be disbanded as it was not an actual company and iPass is not going to renew the contract. I don't know how many users were on the account but it was certainly in the dozens.
That said, iPass has been amazing for the last year and the agreement we had allowed for up to five devices online at the same time, I believe. One device at a time wouldn't cut it for me.
