Well, they're now implementing four dynamic languages on top of the
DLR - not just IronPython.

* IronPython
* IronRuby
* Java Script
* VBx (a dynamic version of VB)

The DLR provides a dynamic type system and hosting environment for
dynamic languages.

The nice part is that the DLR runs on top of the 'Core CLR' which
ships with Silverlight. This means that apps. that run in Silverlight
are secure - so you can run an IronPython console in the browser...
