Thanks for your kind words, Zaq, and sorry for late response.
"provide an online access to your website", that was my version 1.0. It's unable to provided 100% availability, that is, what if for whatever reason you lost Internet connection? For a student who's taking notes for a class or lecture, that's not acceptable.
"many people are not comfortable in using address like
http://127.0.0.1:8600/knb2/. They can think it can be something malicious,"
'popular' mis-perception/misconception, they just need to learn a bit more about computer and the Internet. Or to education/explain to them by us.
Cheers,
