Don't see any problem here. It's pretty much them same as any other spec.
1. Code is versioned so there is no issue with 'Run this code' will refer
to a proper version
2. Comments are versioned as they depends on URL
3. Chat is common for all versions

I will provide pdf version, it's really easy to generate pdf from markdown.
I will do it from so it will
have boost look and feel.

Therefore, theme which has
the same look and feel as any other Boost library
using quickbook. Generated from the same markdown, not fancy stuff, no java
script, etc.

I'm not sure whether I do understand your point. IMHO developers are not
browsing boost libraries trying to check whether
a library might be useful to them or not. It's rather the opposite way.
They have a problem and they are trying to check whether
there is a library solving it. DI is a design pattern and really popular in
other languages and therefore it would be easy to find
by them.

I would disagree with this one. IMHO markdown is well known and way easier
then quickbook. Generating doc is trivial, might be even
done online. Generates doc in 0.1 s. QuickBook is so really, really heavy
in comparison. It's way easier to change markdonw.

The same apply to Markdown. Markdown is well known, really easy and very
popular too.

Don't see any reason why markdown might not be generated from Doxygen
comments. Quickbook doesn't have support for doxygen either
way and any try caused a LOT of pain.

I would say with markdown whatever is possible with quickbook is also
possible just in an easier way.
