Un petit lien pour ceux, qui comme moi, ont oublié ce qu'était Laszlo: http://linuxfr.org/2004/10/14/17415.html(...)

Quelqu'un a un retour d'expérience de développement avec cette technologie ? Je ne parle pas des différents liens que l'on trouve sur leur site mais d'intégration de cette techno dans une page web ?

Et en gros, qu'est-ce qu'ils reprochent à XUL?

Setting aside the benefits of open source for a moment, how are you going to convince developers to choose you, a little-known start-up, over Macromedia and Microsoft when it comes to deciding on a platform?

We've been around longer than Flex. We're deployed on more prominent services, including EarthLink, SBC Yahoo's broadband service, and the La Quinta home page. Some of these sites have millions of users. This is a very stable and robust platform.

So look at the alternatives: Laszlo, a small start-up--and yes, people get uneasy about that--or Macromedia. With Macromedia, the question isn't if the company goes away, but what if it stops supporting Flex? Macromedia has a track record of canceling server products, a whole raft of them--Generator, Aria, LikeMinds, Spectra, SiteSpring. In the commercial world, the size of a company doesn't guarantee the stability of a platform. Macromedia's solvency isn't what determines what's supported in 10 years. Open-source software gets immortality, in a way, if it ever sees adoption. My belief is that you can't get a new platform adopted unless you're open source or unless you're Microsoft.

Take, as an example, JBoss, PHP, Python, Perl, Eclipse to a certain extent--these have been massively adopted and they're all open source. I can't think of a broadly adopted proprietary platform that's been widely adopted in the last five years. .Net is the exception that comes to mind--and that's Microsoft.
