theora - Aug 2008 - handheld theora video camera wish list

What would your wish list be for a handheld theora
video camera?

640x480 25fps/30fps
320x240 25fps/30fps

Record to a memory card (SD)
Lan / WIFI support (auto/manual upload of file on
memory card)
Live streaming (icecast like)
Videoconferencing support
Voip (sip) speex audio

I am bouncing the idea around of developing a handheld
video camera
designed for mobile video streaming

First, I like the idea, and the features you listed below.  

Second, there has been talk that shortly after the release of 
theora 1.0, there will be a theora 1.1 that will not be backwards 
compatible.  Knowing that breaking compatibility is not to be 
done lightly, I trust that Monty is confident that the 
improvements in the quality of the codec that will come with 
version 1.1 will be worth that break.  Anyway, anyone planning 
on developing hardware should take this into consideration.

I did not think of HD resolution
but what HD resolution would you use?

the camera is not made to compete with hard drive/DV
tape based cameras
the camera is made to be in the arena with MP4 memory
card based
cameras

both will be include.
PoE (power of Ethernet) is must for charging / use

I am NOT looking at selling the cameras
the camera well be put under an open hardware license
when we have some working version for our community

I can easily see 720p HD for recording on to a memory
card
but not for live streaming

It would be great if it could output dv via ethernet for use with
dvswitch: http://alioth.debian.org/projects/dvswitch/

Makes it not a theora camera, though.

Actually, something like what you describe already exists. There were
several units made be some russian company (i think) at the KHM. We
played with them a bit during LAC2008.

I know about the elphel's IP cameras
(http://www3.elphel.com/index.php)

the camera need to within the mp4 video camera arena
but must cross over to the network-able/IP cameras

the uploading features are something like eye-Fi SD
card
http://www.eye.fi/overview/

this is the main objective behind the cameras

to create a handheld video streaming setup for a
Community/Citizen media
