 I'd expect that either the kernel routed multicast packets to all interfaces
 (isn't that what routers do with multicasts, contrarily to broadcasts?), or
 the application would send an individual packet on each interface.

Routers have to be told (by means of multicast protocols such as IGMP) 
which interfaces to replicate multicast packets onto.

 Not that it matters, as no one is maintaining ntpdc currently, but I think I 
 found a bug while messing with it:
 
 saturn:$ ntpdc
 ntpdc keyid
 no keyid defined
 ntpdc unconfig 63.240.161.99
 MD5 Password:
 ***Permission denied
 ntpdc keyid
 keyid is 134682920
 
 It seems to randomly generate a keyid and specify it for use, and then 
 prompt for a password for that keyid even though it doesn't exist. And if I 
 do it again:
 
 saturn:$ ntpdc
 ntpdc keyid
 no keyid defined
 ntpdc unconfig 63.240.161.99
 MD5 Password:
 ***Permission denied
 ntpdc keyid
 keyid is 134686616
 
 A different keyid is generated.
 
 Anyway, thanks for the help!
 

it's using an uninitialized variable so the value is random junk. We 
probably should set it to 0 assuming that you cannot use 0 for a keyid.
