What Is An SED? Peer-to-Peer Device?
The acronym SED stands for Service-Enabled Device and refers to any device that is self-aware, so to speak, of its roles and can communicate this info to other SEDs. This type of device has been around since the 1980s, but with all the options in wireless networking available today, a new class of more efficient SEDs is emerging.
While it was originally expected that SED devices would be present in the enterprise sphere (i.e., at places of work) and be part of the IT infrastructure of such companies, the niche of consumer electronics seems to have taken the lead for SEDs. At present, there are only a few device categories:
Kodak and Nikon digital cameras and digital video cameras with Wi-Fi capability that can wirelessly transfer pictures and videos to your wirelessly-connected laptop or computer.- Wi-Fi TVs from Casio, Sharp, Sony, Phillips and others. The idea is that you can move about your home and still watch TV. Your shows will be broadcast from a Wi-Fi base station. Some models even allow you to stream audio and video files sourced from your computer.
We can probably expect to see further categories of SED devices, possibly in the area of medical diagnostic equipment.

[…] An SED Wi-Fi digital camera that auto-posts pictures to an online gallery, along with voice comments. These would be a boon to photobloggers that don’t want to waste time monkeying with a blogging platform and podcasting software. The photog would preview a pic, then press a button to publish live. Of course, the execution of this method either requires that the camera is enabled with a Wi-Fi cellular plan, or near a smart PDA with Wi-Fi, or has Bluetooth and is near a laptop with Internet access. So in the worst case, the photog records audio comments for each snapshot and stores everything on a memory card. Then, when they are able to connect to the Internet, they can auto-publish approved pics and audio. Voila, an audio-photo podcast. (Note: Wi-Fi cameras that can upload to a laptop or desktop computer are either already out at the time of this writing, or will be out soon. However, none of them connect directly to the Internet. Hence, the SED - Service-Enabled Device - designation.) […]
