True, burndown charts are useful in Scrum/Agile projects.

Well, I think for an open source project in general, and also for ACE it will be hard to estimate
the amount of hours that each committer can spend per day or week. It will vary wildly. So
whilst I agree that working with agile methods like Scrum makes sense in a lot of projects,
I doubt that it has much value here. I mean, I don't think it would give you a better insight
into the amount of work that needs to be done before the 0.8 release than by just looking
at the remaining issues.

My rough guess would be that we try to do a release in weeks (not days or months). That would
be our first release, and it would allow more people to try out ACE and provide feedback.

and soon deployment services, and potentially get patches sent your way.

Patches or any other feedback is always welcome. I hope that does not depend on us producing
a burn down chart. ;)

> If you say "yes" (please please please...), it'd be pretty awesome to have a guess at
the "release date" based on looking at the chart burn down and your gut feeling.  Again, I
don't care if it's accurate or not (it's going to be about 10x more accurate than any guess
I can come up with based on ticket flows etc).

I'll keep my estimate at "weeks" for now. :)

You're welcome!
