I intended to call this question: "Are SOCKS proxies still relevant?" but thought it would be too vague.
I know there are various SOCKS proxies that are actively maintained and developed (like Dante), but how are they useful in today's Internet landscape. I mean, there are Tor and alike for anonymity, and solutions like OpenVPN for virtual networking across firewall boundaries. So I'm interested in real-world SOCKS proxies usage examples. What is a good reason to prefer SOCKS to any of the variants above?
