Streaming without an internet?

[tXShooter]

Is there any proven method to stream audio from Reaper via a local intranet to web pages or anything else where a link could be used for listening?

I keep coming across things like ShoutCAST and IceCAST, and even OBS and other streamers, but they all require an internet account.

If there is something, can someone walk me through on how to set it up?

Many thanks!!
