I thought you had mentioned useing STL strings instead
of char* in future code, but maybe I'm remembering
wrong.  Also did you really mean IFileSystemDesc*
&out_sesc?  That * with the & confuses me.  Oh I think
I get it now.  So you would call it like this:

IFileSystemDesc *f = NULL;
a->get_named_child("name", f);

And the pointer f would now point to something new?  I
haven't been paying much attention to this whole
discussion, but why not do this?

... get_named_child(..., IFileSystemDesc &out_desc);
...
IFileSystemDesc  f;
a->get_named_child("x", f);

It would make one less pointer floating around which
reduces chance of seg faults, but like I said I
haven't been paying close enough attention so maybe
there is some reason for using a pointer that I'm
missing.
