How am I doing this? Here is my technical setup:
A computer running Windows 2000 sits next to my bed. It has no monitor or mouse, only a keyboard attached; it's connected to my network via a WIFI PCI card, though I was having connectivity problems at first. At startup, I have a batch file start pinging www.google.com, which seems to kick the wireless connection into gear.
My keyboard has several "multimedia/internet/hot keys" arranged in rows along the top of the unit. I've mapped these to several important functions. After booting the computer, I hit the "Home Page" hot key, which launches a web browser; my home page is set to my Blogger.com "Create New Post" page, accessible directly since I have Internet Explorer cookies enabled. Luckily, the cursor focus automatically sets itself to the posting form -- I can start typing without the need for a mouse. When I'm finished, I can either type Ctrl+S, which Blogger understands as the command to post, or use another keyboard hot key mapped to the same.
At this point I'm finished for the night. I've mapped a hot key to "Shut Down Computer", which I use to shut down the machine.
Sometimes I need to perform real tasks on the computer, such as making sure that internet connectivity is working. When the Blind Writing computer boots, it launches
TightVNC, which allows remote connection and administration of the machine; I can connect to this via my "normal" computer on the same network, using TightVNC client.
