I attended the Sapphire Coast StartUp Camp this weekend. At one point in the leadup to it, it seemed the venue would have no Internet access, so I suggested setting up a MikroTik router with a GSM phone dongle to provide wifii/LAN and Internet connectivity. In the end an alternative was found, but just for the exercise, our team at the camp used my new hotspot, and it worked really well.
Mikrotik plus phone dongle = instant hotspot
