gollark: I *might* be.
gollark: Bold of you to assume I did any anyway.
gollark: Hmm, the most convoluted and reasonably practical way to do this would be to... use my RTL-SDR to listen to Radio 4, but hook it up to my server, run it through some kind of audio compression thing, somehow figure out how to stream the resulting audio over HTTP, then stick that on my website.
gollark: Hmm. I should really listen to these announcements... what's the most convoluted way to do that, I wonder.
gollark: Wait, the UK?! I live there!
