Tim, throughout this post, you're way out of line. The s/w I have already
built for this client works just fine. It's not a matter or not having the
tools or not knowing how to use them. Pay attention to my question, don't
make up your own based on your own inaccurate assumptions and answer those,
please. Stick to the topic.
4) Don't be afraid to reuse existing technologies: could installing
osCommerce on a $3/month web-server and tweaking the PHP code have sufficed
for what you need? Could you have used Django+Satchmo to get yourself up
and running with proven code, tweaking what you need? I remember you
dismissing the suggestion to use existing web-frameworks.
Bringing that up again, are you? I was all but done with the shopping cart
when you suggested I re-invent the wheel based on another technology. Yeah,
sure, throw out 10,000 lines of the 12,000 line program so I can rebuild on
a new technology. Brilliant, that. Thanks for the suggestion. Now, can we
get back to my question?

Yeah, that's where we should have been all along, Tim.

Now you're talking.

Ah, so you *did* recognize what *my* question was! Good!

True. I ended up taking a bath on it, and I believe that was merited since
it was my first client project. Now, I'm dealing with scope-creep and trying
to work my way out of it, and looking ahead at how to avoid complications
like this in the future.
