Prep
PT spec revisions — how to proceed? Is it better to collaborate with other groups, or go it alone? Other groups have other needs, may do/require complications not needed by Tor. On our own as a Tor-specific project, we lose any pretense of "pluggability."
The API definition is a real benefit of the PT 2.0/2.1 specs, especially for iOS. The rest of the 2.0/2.1 specs, such as the revisions to the IPC interface, we're not so sure about.
