Quest for Multi-Development Web Platforms: Titanium, OpenLaszlo or others if any ? Which to prefer?

In my quest for Multidevelopement Web Platforms (Desktop Browser and Mobile), I have encountered only 2 :

• Titanium
• Openlaszlo

Only two. So are there any others ?

I have looked at Titanium, seems very promising bu开发者_运维技巧t I wasn't even able to create a project as It crashed on my windows 7 PC.

As for Openlaszlo I heard about it years ago; OpenLaszlo can generate both flash and html. I wasn't really interested until now as I didn't really have any real need for being multiplatform. Flash alone could suffice with Web Desktop.

Did you try any of them ?

I'm looking for .NET and Java.

ASP.NET MVC is what you would call a "multi-development platform." The Mobile Browser Definition File is ideal for customizing behavior across different mobile phone models.
