Embedding IronPython, built-in help command, my CLR objects

I'm embedding IronPython (2.6.1) in a C# assembly and exposing several objects to scripts which are executed with PythonEngine.ExecuteFile. I expose them either with

scope.SetVariable("SomeObject", new SomeObject())

or

engine.Execute("from MyNamespace import SomeObject", scope)

depending on how the scripts use them. My application assembly is added to the engine with

engine.Runtime.LoadAssembly(Assembly.GetExecutingAssembly())

Now a script can execute help(SomeObject) and dump the nice little help info(*), however it's incomplete. None of the object's events or properties (public of course) show up and many of the 'built-in' members are missing as well.

Here's the odd part; If I fire up ipy.exe and execute the following:

import sys
sys.path.append('<location of my app>')
import clr
clr.AddReferenceToFile('myapp.exe')
from MyNamespace import SomeObject
help(SomeObject)

I get a different dump, complete with all the missing members!

Why do the two differ?

Bonus question: Assuming I get it working correctly, is it possible to add descriptive text on my CLR objects to the output of help()? Like you can from within the script, on your python-native types? My first guess was the DescriptionAttribute, but that didn't work.

(*) Obviously a final, working script wouldn't do this but it is exceedingly helpful while writing/testing the script.

Here is a complete console program that illustrates how to import the site which replaces the usless internal help() with the standard python library help().
