"Hola dynamically uses both Internet connections, each one according to its connection quality and bandwidth. Hola splits up the HTTP requests - some go to one connection, some to the other, and large ones are split up to both of them at the same time!"
This seems to be like a load balancer - one example of new generation of connectivity balancer is the new Connectify Dispatch which will allow you to use bond multiple connections on your PC.
The difference here is that Dispatch does it for any TCP traffic, while Hola seems to do it for HTTP traffic only.
I am keen to try Dispatch but there's no trial, only a "30 day money back" guarantee...
