I'm watching https://www.youtube.com/watch?v=7mqkTFq7Ekg specifically the part about DSVD sneaking in a second data channel, and thinking "this would be useful for a backdoor, in some kinda 199x hacker movie"

like, you dial into some system, it's sitting there at a console login prompt, and the remote modem supports DSVD except instead of sending digital voice it's been connected to another secret console login

@grawity you absolutely can

I have in fact implemented this, over eduroam. mostly because I was wanting to test new EAP methods, but really any data could go over the TLS tunnel between you and your auth server

@q yeah, it makes sense, especially given most of them just do TLS on the outside... wonder what the rate limits are, though. do the proxies put any restrictions on how long you can chat? I think I remember freeradius having a timer of like a minute or so?
