Well, the way I see it, ? is already there for finding information about 
objects.  This seems like a quite natural extension: when you don't know the 
actual name of an object, this can help you find it.  For example, this 
(mockup) use looks very natural to me:

 > plot*?

['plot','plotfoo','plotbar']

 > plotfoo?

... plotfoo plots foos very nicely...

While the above case is probably best handled with plain TAB completion, for 
cases where the unknown part is at the beginning of a name, TAB won't help you.

So it doesn't feel to me like introducing anything new (? is already a special 
prefix, it has been since ipython was born).  Rather, it's an extension to the 
functionality of '?' which seems fairly natural to me.

Cheers,

ps - Ville, what came out of your win32 experiments?  I'd forgotten to ping 
you again on that, sorry...
