	Bonobo stream does do seeking; it also has a 'truncate' method, +
commit/revert - although having transactions in the base interface is
prolly a mistake.

	I personally think that having a Stream API that is not async
immediately cuts you off from it being used as a Network stream API, and
thus from being really useful for gnome-vfs / CORBA. Thus having a file
descriptor (or some more abstract source ) that you can add to a glib
mainloop seems vital to me.

	I share Jody's scepticism of having a stream that is all singing /
dancing. I'd prefer to see two interfaces: ReadableStream /
WriteableStream or somesuch - plus perhaps a seekable interface.

	It would be well worth looking at:

	http://ooo.ximian.com/lxr/source/api/udkapi/com/sun/star/io/

	for the OO.o stream APIs; particularly separating: seek/truncate/length
off into a Seekable interface is rather nice. One imagines that you
could use 'GInterfaces' to do this - assuming the performance hit isn't
too much of a problem. Some things are worth avoiding like 'available'
on the XInputStream though.

	FWIW,

		Michael.
