The approach is nice, the problem being solved is real. Hopefully paying customers will flock in.

The question: is mummify.it itself going to go under some day?

So I'll wait for an open-source analog of this service, to run on my own tiny server. (Or carve some time to write it myself, of course.)

There already is an open source analog:

Wget is definitely a good start. What's needed is a shiny and usable UI, ways to catalog / tag / search inside your saved data, and a painless installation process. This could use come work.

I think Evernote was also intended to solve this. Unfortunately, it is also proprietary. So, there is definitely demand for this.
