While it's not much.....For what it's worth.....

I just completed the "clientVersion" and "authentication" services for QBWC 1.5.

The major difference....(from all the work I've viewed/downloaded like qbis)....is that I'm doing the complete WSDL generation within nuSOAP.
This includes the XML Array parsing that apparently has driven everyone insane
in the past.
This also means that it will run on old PHP4 installs as long as SSL is running.
My needs were not as heavy as the QBIS system. I just want to put transactions
in the table....in both directions with logging.

So yes.....I'm working on it independently....with a completely different
approach to the requirement......and I have a long way to go......
