        My immediate reaction is that we're safe till 2056... there are no
elsets with epochs before 1956, after all.  By then, it's not my problem.  I
don't expect I'll give a darn if I've actually lived to116.  ;-)

        Okay, a seriouys answer to this one.  There is much more leeway in a
given number of characters using aan alphanumeric format.  After #99999 we
should go to A0001-A9999, then B0001-B9999, and so on.  That's enough for
25,974 satellites!
