[Icecast] can there be only one?

[Carl Karsten]

I am gonna get a vga grabber box for capturing presentations (like local user 
group meetings and all 72 hours of pycon08) and figure out some way to stream it.

Now to pick one out... the only one I have found is
https://ssl.epiphan.com/products/product.php?pid=1

It seems to do what I want, but I would like to shop around - but so far it is
the only one I have found.  Requirements: capture 1024x768 vga signal.  (not 
S-video, not software, not a cam corder.) output something that can be streamed 
to icecast (or converted to something, duh.)

Anyone know of any?
