Marc Blanchet is looking into it. See message below.

- yes, we could.

all this is good.

but:
- I'm still investigating deep inside the code to see all the implications 
of the port to ipv6. The more I open, the more the forrest is deep...
- When done and some basic porting work done to validate, I would be in a 
position to write such guideline, including a possible paper describing the 
changes and proposals for future ip-independent asterisk. Until that time, 
I'm not sure those kind of guidelines will be useful, since I'm pretty sure 
they will be ignored and might be subject to change (other than the basic 
ones). I think it makes more sense to have a comprehensive view of the 
changes and have some discussion on it, before starting to change things.
- I'm not committing to any timeframe. sorry. Have a day job ...

yeap. but I would see this as "phase 2". Phase 1 would be to have v6 
supported everywhere, same level as v4. inter-version/proxy/... would only 
make sense after.

sure we/you could. I'm not yet ready to write something other than I'm 
working on it. I will be happy to provide content when appropriate.

news later when I'm making sufficient progress.
