XML-RPC Wordpress Upload Part II

I am looking for help developing a desktop tool or a enhanced excel workbook to upload multiple posts to multiple wordpress blogs using the XML-RPC standard wordpress connection. If designed as a desktop tool, it would be similar to BlogJet but would need to support importing a CSV file or directly accessing information in a excel workbook or MS Access DB. If designed as an Excel tool, it would need to leverage VBA to make the connection and send data. The solution needs to batch through several hundred posts (title, body, categories, tags, time/date stamp) and publish them to several hundred different blogs. It needs to store user/pwd for all blogs. And, it needs to keep a log file to track success/failure of each upload. Really, the best way to see what we want is to download the free version of BlogJet and imagine adding the functionality to import 200+ posts at the same time for batch posting. Thanks! Rich
