Steve,
All three are good questions. Since I am not really in
business for myself, I am hardpressed to give a meaningful answer to
the cost question. I would certainly think $100-250 is not out of the
question, compared to the costs of accessing network mail services,
the investment in my home/business computer, word processing software,
and other costs of setting up my business. Still, I suggest asking
some folks who really are in very small businesses for their thoughts.
I would think that a notarized copy of my business license, articles
of incorporation, tax returns for my business or similar stuff is not
a big deal and not very expensive at all. As for accommodating growth
at STK Associates, note the model I gave. I said the STK Associates
would become a CA and I would have a certificate issued under that CA.
Depending on the level of assurance which the PCA policy requires, I
might be able to do the certificate issuance in my home (act as my onw
CA), or the co-issuer model we described in the RFC version of 1114
might be an appropriate way to keep down CA costs but offer high
assurance for certificate issuance. In either case, issuing another
certificate to an employee of STK Associates should be relatively
cheap.
