[Icecast] VGA Capture

This is somewhat OT, but just a little.
I want to capture live (5 fps?) 1024x768 VGA and make mpeg or something I can
stream over the net.
The application is this: Developer meetings and conferences. "all" speakers
bring their laptops and hook up to the 1024x768 projector. I want to broadcast
that over the net. (I may point a web cam at the presenter too and have that as
a 2nd feed.) I do not want to load anything on their laptop. I 'know' it is
easy, cheaper, and better in some ways, and it may even happen in some
instances, but for the most part, I never want to even ask a speaker to do it.
There just isn't enough time to to make sure it works, etc. A hardware based
solution is much more ... good.
The plan is to have a laptop or small PC sitting under the projector that
somehow gets the same VGA as the projector. Some projectors have a VGA out, not
sure how standard that is. I can deal with an external device that uses USB or
Ethernet, or a pci/pcmica card in the box that will do the encoding.
I found this: https://ssl.epiphan.com/order/order.php?pid=1 - that will do what
I need, but $400 is a bit much (I need about 5 or 10 for conferences that have
multiple sessions going at the same time.) I am kinda doing this on my own -
the first step is to get one for the local user group meeting I attend. If that
works out, then I may get some more and loan/rent them out. Thus the desire to
find a cheaper solution.
I found things relating to KVM over IP, can't figure out if these will allow me
http://okvm.sourceforge.net/kvmoverip.html - pretty sure that requires a pci
card in the box generating the video (so no good.)
Thanks for taking the time to read this - any pointers welcome.
