Unfortunately, as far as I know, the Microsoft Loopback Adapter doesn't
support packet capture.  You'd have to ask the WinPcap developers:

	http://winpcap.polito.it/contact.htm

about that, however - Ethereal's capturing is done, on UNIX by libpcap
and by the OS mechanism libpcap uses, and on Windows by WinPcap and the
OS mechanisms WinPcap uses, so that's the code that controls on what
interfaces packets can be captured.
