I.e., because the names, at least in modern (i.e., NT 5.x) versions of 
Windows are horrible ugly strings with a GUID in them, and not at all 
obvious, unlike the way they are on UN*X (and somewhat on NT 4.0)?

Run "tethereal -D", which will enumerate the interfaces it knows about. 
 It'll list some really ugly names starting with "\Device", and should 
also give a somewhat more human-readable name.

(Ideally, Ethereal would also support "-D", but, just as with "-v", we 
might want to suppress GUI stuff, such as the splash screen, as those 
options would just print stuff and quit.  We should also support 
numerical interface IDs in Ethereal's "-i" flag, as Tethereal does, so 
you don't have to type the ugly name.)
