The roadmap can be found
[https://www.cl.cam.ac.uk/~sjm217/papers/tor12pluggableroadmap.pdf as a
PDF] and
[https://gitweb.torproject.org/sjm217/torspec.git/tree/refs/heads/project4679:/proposals/ideas
/xxx-pluggable-roadmap in git] (branch project4679, commit
bb207c619310e450060ce39d6343c4742f26488f).
In summary:
Of the currently available pluggable transports, obfs2 is a good default
due to its efficiency and resistance to blocking. StegoTorus offers
alternative pluggable transports which are significantly harder to block,
but come with a much higher overhead. Suggestions for future development
include: efficiency improvements, splitting and joining Tor cells to
disguise Tor's distinctive packet-size probability distribution, efficient
ways to hide ciphertext in compressed data, hardening obfs2 against a
passive adversary, and designing a HTTP transport capable of traversing a
proxy server.
