I think it would make sense to re-implement the info program
in JavaScript  By that I mean adding event handlers for the
keystrokes of the traditional info program.

Some tweaks might be needed to makeinfo - if nothing else so the
generated html loads the 'info.js' script.

This could be an appropriate Google Summer of Code project,
I think.

The info program when invoked with appropriate flags would
just be responsible for locating the html file, and loading the
file using a specified browser - by default the default desktop browser.

I've been working on terminal emulator based on Web technologies:
http://domterm.org/
https://lwn.net/Articles/670062/
When the info program is started from a DomTerm terminal
it can do the html rendering with JavaScript UI directly
in the DomTerm window.  More precisely, the info program
could send an escape sequence to DomTerm to create an iframe
and load the html documentation in the iframe.

This would be a nice way to get a seemless and familiar info interface
- but with all the HTML layout, fonts, styles, and images.

The normal info keystrokes would act as familiar - except they
would control the document shown in the iframe.  Clicking on an internal link
moves around in the document, perhaps loading some other html-info file.
Click on an external link (@uref) would (by default) load a document in the 
user's
default browser, though it could optionally load it in the iframe.
