In other words, have you increased 20-fold (or is it 20^2 for an image) the number of packets that are going to be sent to increase your framerate by 20 times?
For some reason I thought the communication protocalls were sancrosanct - that is I thought we weren't allowed to touch them because of bandwidth concerns. I had thought that was why they limited the dashboard to a 1 hz update, though I might be wrong: you know what they say about assuming.

I'm not sure either. The TCP stream
tries to send an image pretty fast, but fails. Also it implicitly fragments, but I do not know how this affects socket I/O. I know that I use ~1MB/s for 640x480@30Hz with Jpegs drawn on the computer, but they are much larger than the camera's Jpegs at no compression. I'll post bandwidth usage for each image size tomorrow.
