Valid questions, but, as I understand, not the kind of TeX service Chris
provides. You are talking about giving access to TeX engine on your machine
to someone coming from remote. Chris' customers use their own TeX engine on
their own computer/server. Chris doesn't have any control over this TeX
engine. Maybe Chris could invest thoughts about preventing users to input
code (product names, product descriptions and such) containing potentially
problematic TeX commands (like the dreaded \write18), but that's a
completely different toppic from the aspects of using TeX as backbone to
accounting software discussed up to now. It might even be moot unless the
accounting software grants permissions the user doesn't already have.
