	Right - we're not interested in this in the ORB; possibly something
like this belongs in libbonobo - but then the PropertyBag interface does
something similar.

	Ok - we can do this without the IR, with our internal typecode
registration stuff then I guess.

	Ok; I just looked at this again, and I think we could make an async
interface out of it without too much pain; since the NVList is an
interface; either way - it would be _most_ helpful if you could extract
the DSI information, interfaces and types from the spec. and post them
here in text form so we can wrestle with them more effectively [
postscript / pdf suck for almost everything ].

	Can you see http://ooo.ximian.com/ooo-build.html - pwrt. the
instructions for generating a crypted password.

	Thanks,
