Circumvention research can probably learn a lot from steganography
research. Most of the "mainstream" research on circumvention (read: the
work I'm familiar with :D) is in CensorBib:

However I've been meaning to see what else we can learn by bringing
related research into its scope. There's a thread of research by
Sebastian Zander et al. on covert channels that hardly intersects with
circumvention research; it would be a good contribution if you could
determine to what extent the two worlds can be joined. For example
"Reliable Transmission Over Covert Channels in First Person Shooter
Multiplayer Games" predates Rook and Castle. They developed an
evaluation framework that to my knowledge hasn't been applied to
circumvention protocols.

"Provably Secure Steganography" by Hopper et al. could be relevant to
certain kinds of circumvention protocols.

The traffic-obf list is a group of circumvention researchers. They are
scheduling biweekly meetings on IRC. You could discuss some ideas there.
