I realise there's some irony in an amateur pseudo-lawyer (me) being
critical of analysis from other amateur pseudo-lawyers -- but the above
sentence relies on the vague casual term "promise", which should not be
confused with the legal term "contract".

_Regardless_ of whom a "promise" was made to, that itself doesn't
suffice to establish an offer and acceptance, supported by
consideration, etc.  Thus my point to Mr. Mahesh T. Pai (Mr. "violation
of an undertaking") and others.

Quite so.

This hypothetical _differs fundamentally_ from the case Guilherme
raised.  Billy is reusing third-party code under licence.  The person in
Guilherm's scenario was not.  I just note the fact in passing.

My understanding of the unauthorised practice of law statutes is that
analysing hypothetical legal situations does _not_ constitute practice
of law.  Otherwise, laymen would not be able to discuss legal matters at
all.  You thus wouldn't need to worry unless Billy and David are real
persons in that situation, and you're helping them with their respective
specific problems.

That is correct.  (Of course, separately, David and Billy might have
business relationships such that contract or promissory estoppel might
possibly apply, but that is not part of your hypothetical.)
