Not only NO, but HELL NO...
I've been to too many venue sites where WIFI and cell was not extant.
Some of my venues lately have been the tops of tall buildings where cell transmitters from other carriers jammed my cell.
~
In one case, Bozeman, Montana... The local carrier was not my carrier and there was NO roaming arrangement for both the cell and cell modem I take with me on gigs..
~
The gig on the bank building in NYC was a case in point, no net access, wifi useless, two cell sites at 500 watts each on adjacent corners of the roof jamming my cell, and most VHF/UHF two way radio channels useless (Had 18 channels in my radios, had to manually hop frequencies to avoid Spanish speaking taxicab dispatch while talking to our other site on an adjacent building) ... Not to mention bank security breathing down our necks over ANY digital device on our person.

I like Tammar's "Reverse Activation" solution, well, sort of. I'd rather have a "one time pad" style keygen like Paypal used to issue where it has a LCD on the side with a pseudorandom sequence generated number based on an internal clock. ie RSA SecurID
only put the clock on the FB4 etc..

BTW, USB Dongles are bad in one respect, DJ's often swipe them on stage, thinking they are getting your music "set".

People are biblically evil. There is no easy way, but I'd like my account to stay active for a minimum of sixty days. Don't get me started on Windows Updates delaying visitor presentations to large groups at the day job. (yes, I know there is a 30 day delay if you know where to look)
~
I can tell you cases of being in highly secure sites too, where remote activation or even a laptop for diagnostics for "day job" tools was nearly impossible or banned. Not everyplace has the NET.

I should have rented the space under my name for advertising.
