 Replying to [comment:13 nickm]:
 > The crypto-instrumentation part of this is in for Nov if we can do it.

 ACK. I have a branch that needs cleanup which adds the basics (build
 system integration and templates) to add any kind of low level
 instrumentation that we can then hook a tracer, shadow or any thing we
 would like that collect the data. I'll make sure to have it available soon
 for the crypto work to start.

 For the crypto instrumentation, I'll need a Yawning or nickm for this.
 Basically, if you guys can give me callsite you want to instrument that is
 precise location in the code and payload to record, I can start adding
 them to the branch so you guys can see the mechanism and design involved.

 Let me know if you would like to proceed differently. FYI, I plan in mid-
 November to work on this with Rob to instrument the connection buffers for
 his experiment and for that to be upstream also.
