I'd like to question that 25e6 figure.  It's one "mid-to-large" (to quote
you) company in the US for every 10 inhabitants.  Really?  Is it perhaps
a world figure instead?

If we want a hash that's easy to compute from the company name, use the
first three characters of the name, not something which requires external
knowledge.  It certainly does not solve the name-conflict problem, but it
does provide sufficient division of the namespace to make the load on
any one branch bearable, both for name service and for registration.
