Private VPN compression for faster Internet

What I found to be a good solution for me was Ziproxy.

It's an http compression proxy that is able to compress big html assets, like images, so that webpages are lighter. As it's a proxy, it works with or without a VPN. It's also very easy to configure.

Nomachine works really well. It can compress audio too.

X2Go is not bad, but it can't compress audio.

These are remote desktop solutions, but you can tunnel them through SSH.

I've tested both of these with the server on EC2, and with the desktop sized to fit whatever phone/desktop screen I'm using.
