I'm curious about how .NET will affect Python and Ruby applications. 
Will applications written in IronPython/IronRuby be so specific to the .NET environment, that they will essentially become platform specific? 
If they don't use any of the .NET features, then what is the advantage of IronPython/IronRuby over their non .NET counterparts?
It would be cool to run Rails/Django under IIS rather then Apache/Mongrel type solutions
How will Python and Ruby applications be affected by .NET?
