Romain,

I am CCing the Linux-HA list here, as this may be of interest to the
non-DRBD crowd as well.

This is a work in progress, an as-yet rudimentary Heartbeat User's Guide
is in my personal hg repo at http://hg.linbit.com/florian/linux-ha-doc/.
There are no nightly builds or anything for this yet, but as soon as
rendered documentation is available it will be announced here.

Undecided at this point, but most likely somewhere on www.linux-ha.org.

Yes, you can. I am aware that the UG needs an update in that regard.

Starting with the final Heartbeat 3.0 release (currently 3.0 is
classified as beta). Which, as previously announced, is planned for January.

Please note: Andrew has already built some Heartbeat packages for
Fedora. These are numbered 3.0.0 and 3.0.1 but constitute current
snapshots of the -dev Mercurial repo. Because of this, the initial
"official" version 3 release will probably be named 3.0.2. Andrew is
aware of this and has promised us to not label any of his builds 3.0.2. :)

I hope this clarifies things. If it does not, please don't hesitate to
come back with more questions.

Cheers,
Florian
