Multi-mastering with dynamic updates

[arcan666 at free.fr]

Hi all,

Like a lot of people over the web, I am looking for a clean multi-master (multi-primary) solution that allow dynamic updates.

And like a lot of people over the web, I haven't found anything interesting. 
Google hasn't been friendly for now :/

I have tried :
- bind-dlz over brbd doesn't allow dynamic updates.
- rsync the .jnl files needs a rndc reload (it's not clean).
- slaughtering virgins for bind's god(s) is a little dirty (well, I haven't tried this [yet]..).
- ...

Can someone give me a hint ?

Thanks.
