We are working on improving Tor's pluggable transports specification: https://spec.torproject.org/pt-spec
The goal is to make the spec useful to more people and fix issues that have accumulated over the years. For more context, have a look at the following ticket, which we use to coordinate this effort: https://bugs.torproject.org/29285
Before changing the spec, we need to understand its shortcomings and what issues implementers have run into. For those of you who have experience with the spec -- either Tor's version 1.0 or version 2.1 maintained by pluggabletransports.info -- please let us know:
* What version of the PT specification and what library implementation (if any) are you using?
* What has your experience been with the PT specification?
* How would you improve the specification?
Thanks, Philipp
