Some guys in Miami with a T-1 and who then carry a drive into Cuba. There are almost as many flights between Miami and Havana as between Miami and New York. The only restriction was that you have to be Cuban to get on the plane in Miami--there are but few exceptions.
It's been so long since I even heard anyone mention T-1, I had to look up the speed, 1.54 mbps. I remember in the early days of dialup internet access with 14.4k when this was seen as a very highly coveted connection to have access to.
