The business use case dictates efficiency.

A machine can process a regular expression pattern match for a namespace
prefix much more efficiently than having to create a large tied hash and
comparing it to an internal hash to recognize a preferred taxonomy.   

I propose a comprimise.  We use the DC 128 bit stuff for the GUID but
still allow it to be prequalified with a namepspace prefix to represent
the vertical or taxonomy owner.  David's suggestions of a 26 base 3
prefix should be more than enough.
