Cool, I'll send out an update after I find out more.

Unfortunately there's some internal process required before we cross that hurdle that we've simply been putting off.

Having a 'patched where necessary' distribution of the standard library
come with IronPython would be *great*.

+1000 to that idea.

I was also thinking that there should be a preexisting way to do this in Python but I don't see an upper function that lets you specify the locale or force it to do so against an invariance culture.  Maybe just a call to string.translate instead?
