Interesting recording scheme. Was the interviewee the one recording in this case? Good idea!

That gives me an idea for even better quality (albeit double the work,) you could have both sides record the conversation and splice them together afterwards.

Question to Mr. Dexter: If you use a look-aside buffer to copy data, and pass that, instead of the original userspace buffer, to syscalls, how do you handle syscalls that expect userspace pointers and copyin() etc. data?
