SSH Proxy instead of VPN?

Having tried becoming a VPN provider and it not working out (way too much competition). I've been thinking of other things and have come up with the idea of publicly accessible SSH Proxies.
Idea is to SSH into a server (you won't get shell access) and set your browser to proxy internet traffic through the SSH tunnel.

Anyone interested? I've currently 1 server in Poland running Trisquel.

Basic info:
SSH uses Eliptic Curve keys.
User is to generate their own Eliptic Curve key pair.
SSH to the server (there is no shell access), add public key (using the option available, see screenshot).

Connect using: ssh -p 443 tuxproxy@server-ip -D 1080
Then changing browser proxy settings to SOCKS5 127.0.0.1 port 1080
