Yeah, thats doubtful but you can run your own on a VPS (OpenVPN and DD-WRT router) and can push several hundred mbps no problem and probably closer to 500mbps; assuming the VPS is connected via gigabit.
This is exactly what I thought when I saw read this story. Just combine this gigabit service with an Amazon EC2 reserve instance.
Remember that EC2 charges $0.12/GB for data transfer so $30 only buys you 250 GB. I suppose if you used a spot micro instance and only sent not-already-encrypted data through it you could save money.
Linode, DigitalOcean, etc
I wouldn't be surprised if they try to sneak in a provision in the Terms of Service prohibiting VPN use.
They would have to distinguish between my employers VPN traffic and other VPN traffic. If I cannot remote to work their service is a non-starter.
