[IronPython] Hosting Script Debugging

[Dan]

I am looking at using IronPython 1.1 as a script
hosting for an application written in C#. I would like
to provide the users of the scripting language full
featured functionality for debug of user created
python scripts, much like excel does with VB Script.
Features I am look at are:
1 - Line Number for code executed. I would like to
know and report from my C# code what line number of
the python script called my C# function.
2 - Breakpoints
3 - Step through, jump to code within the user
supplied python script. 

Any suggestions on where to start?

Thank you,

Dan
