Exactly, you just need to reduce the friction level to a certain point. Saying it requires it's own web server sounds like a chore, but Mac OS X comes with a web server built in. You could in theory run your own local Wiki. Or someone clever could sell cheap instances powered off Amazon/Google/Heroku/cheap VPS host with a custom web frontend that does the heavy lifting.

TL;DR good companies make life easy for people who want it without hassle.
