I opted to use the flat interface, mainly due to the fact that without compiling my own instance of php, my host does not support the XMLRPC functions for php.
At any rate, I have the basic functionality working. I can add a new post automatically via the flat interface. I intend to add functionality to edit and delete when my main site changes as well. Currently having no machine at home rather limits my development time.
Just wanted to say thanks to those who had input, and let you know the progress.
If there is interest when it is all working, I will release it for general consumption.
