One definition of "the swamp" from draft-ietf-grow-rfc1519bis-00.txt is:

   "Note that, as defined, this plan neither requires nor assumes the re-
    assignment of those parts of the legacy "class C" space that are not
    amenable to aggregation (sometimes called "the swamp")."

Since we're talking about IPv6, I'd think it would make sense to 
generalize this definition to be the unaggregatable prefixes in either 
global address pool.
