Excuse me for asking here, I'm not even sure of the correct vocabulary.
I want to be able to plug my PC into a wireless router - or some other magic box - so that anyone with a PC within wireless range can see a WebSite (ok, not really a WebSite, it's not on the web, just some local HTML) contained on my PC. No internet connection needed or available.
So someone sees my WiFi as available, connects, and can then access and interact with what looks like a normal WebSite.
This isn't my normal scene, so I probably have the terminology wrong. For all I know, it may be trivially easy or impossibly hard.
Cheers
