Indeed. And the problem isn't even new. The ITU has always assigned
callsigns blocks with three characters (such as DAA-DRZ to Germany). It
was just a courtesy to the ham community that only 1 and 2 character
prefixes were ever issued with Swaziland (3DA) as the only exception
I know of.
One of my crazier ideas to deal with the issue of the longer callsigns
was using a hash value instead. The probability of colissions is low but
how to do the reverse mapping from hash to callsign ...
