I have my first remotely administered network appliance set up now.
It's a picture frame I bought for my grandmother for Christmas from ceiva
I went to the website in advance, armed with the serial number of the device. I was able to set it up and configure it so that when she plugged it into her phone line, it was able to dail an 800# and configure itself with settings, including local phone numbers for her area.
I can go online and see what pictures are in the machine now, pictures that are queued to go in the next time it dails (in the middle of each night) and so forth.
It's pretty fun. I have to find out how she likes it.
