I’m trying to automate as much of the WP admin stuff as possible, and the reasons for that is of course because I’m lazy, hehe. Seriously, it takes a lot of to manage 20ish of blogs (on different servers and different hosting accounts etc) if you are supposed to go through the admin GUI  and login/click around etc for each of them.

I have my own Windows client for managing it, where I basically select a blog from a dropdownlist and then by utilizing XML-RPC calls do my stuff. One example of where the existing RPC interface is not enough is blogrolling, therefore I created my own extention plugin for link management. I have a lot of more of these type of RPC extentions, but they are simply not ready to be published yet, but I will.

In the meantime waiting, why don’t you download a really basic remote blog manager program, which gives you the (C# sourcecode is included) very first skeleton program for you to build upon. While the actual article writing GUI is a joke compared to other blog clients, say LiveWriter for instance, the point is that is is totally expandable. And YOU decide on how to expand it. If you know how to implement some XML-RPC on the server side then there is NO limit on what you can achieve from your OWN blog client. For example I am experimenting on some options manager. So please feel free to download and try it out - the code is very simple, but has no error handling at all, but, hey, at least it’s a start.
