I would suggest Opa: http://opalang.org

Isn't javascript blocked by your browser? (Are you using IE6?)

Let's get a bit technical, we really expect you to share with us.

I should add that this conversation is about the Opa platform (http://opalang.org). The feedback we are currently gathering from the community is going to play an extremely important role in shaping the future of Opa.

Although I could see it as an international ID, I don't get the point of a 'world passport' to cross border.

If your having several instances load-balanced, you can easily update your site, one instance after another. No server runs mono-process. What do you think?

If it works like this, it's a great feature. But what's happening when in an update the database structures are changed?

There's no easy answer to your question. Although Opa raises warnings when it detects that the databases your accessing/trying to modify have changed, I guess you'd have to think of a migration process anyway.

What is your best practice so far? (and your expectations :p)

Has anyone related my post to that one ? http://news.ycombinator.com/item?id=2458556

Definitely looks familiar :)

I'll be sure to write a blog entry on the topic soon.

Caveat: Both the OP and I have been working on Opa.
