I asked about that at one point, but Tony did not want to. If I remember correctly, it was either a matter of:

a) blatent commercialism and requests for bribes being made semi-official
b) not wanting to blast Tom's name and phone number in other web places
c) some other reason that I do not remember at the moment.

I am sure we will know soon. I know there was a thread about this, long ago. Searching...
