In fact, that work has already been done: http://stackapps.com/questions/3610/stackdump-an-offline-bro...

If someone could make this into an Android app with wifi hotspot functionality that would be awesome.

I wouldn't mind doing that, but not what sure you mean with "wifi hotspot functionality"?

I'm not sure what the original poster had in mind, but what I'm guessing (and what I would want) is making it a web UI so access could be shared easily to other people or devices.

I took it to mean "put it on your phone and let the phone serve it"

Yep, this. So I hit a button in the app, fire up the laptop and enter a url like 146.162.0.9:2020 to browse the offline stackoverflow.

An example of similar hotspotting would be the ftp app on f-droid.

> at least 20-30GB of space

What would be good would be if there was an easy way to filter the local database for specific tags before putting it on the phone.

Why not just server it on your laptop, locally?

This actually sounds quite interesting. I might just go and do it. The question is, will SO approve?

Edit: I'm guessing SO probably won't have an issue with it.

I have used this iPhone app while programming on the trans-siberian express:

It works but the experience is terrible. I'd be happy to throw money at a better app, in case anyone here is bored... :)

Could it be converted into a ZIM?

Thank you. Stack Overflow is like the wikipedia of tech knowledge.
