With minimum speed of 15mbps to access, it's like impossible for students in developing country which i think they more need service like this for study, research, etc.

For example in Indonesia, in my campus internet speed is only about 3-4mbps.

Scaling infrastructure is hard, i think the future of service similar to paperspace is not a bunch of feature that they offer, but it's more about how they can optimize data compression to deliver full of experience with low internet speed. That's the key to own big market.
