I'm not sure the w.bloggar (or any other) pc-based blog program is going to work. w.bloggar tries to talk to the server upon launch. If that happens to be while I'm disconnected, I have to wait for the network error. In true developer fashion, I'll probably try to create my own tool.
I have dasBlog loaded on the laptop, so I'm thinking that I post to the local machine. My tool will reconcile the entries on the laptop with those on the server.
UPDATE: Microsoft just release the Offline Application Block, which is exactly what I need. But, I don't know if I have the time for a full-featured winform application.
