What are you options for dynamically-typed .NET web development at this time?
Ruby on Rails with IronRuby?
Django (with a few alterations) and IronPython?
Don't feel like going the Phalanger route. I'm done with PHP.
I assume there is some way to make ASP.NET MVC more dynamic... but can you fully exploit that in .NET 3.5? There is the work Haack/Lam/Schementi did. Post Anyone looked close at this?
What can FubuMVC and MonoRail do with dynamic languages? I'm not very familiar with them.
There is a full implementation of ASP.NET MVC with IronRuby. This has a much more dynamic feel than the regular ASP.NET MVC.
MVC is a pattern about separating responsibilities so I don't see what that has to do with more or less dynamic. From what I get from your post you want the dynamic typing goodness and that stuff is implemented in ironrubymvc. http://github.com/jschementi/ironrubymvc
You can also use Rails with IronRuby at this moment so that would be another option for you to use, but the dataaccess may need to be revisited though to work with .NET or you need to use one of the .NET OR/M's.
