Probably not the most practical attack, but it is very possible to MITM the connection between the keyboard itself and the motherboard.

A similar project is rr[0], which is freely available. Like you said, I find that reversible debuggers are a huge improvement over regular debuggers because of the ability to record an execution and then effectively bisect the trace for issues.

Intel has an implementation of this technique here as well:

Yes, this is on a single 8GB 2667MHz DIMM in a laptop.
edit: For dual channel RAM, I would suspect the throughput depends on how the kernel decides to map physical memory to virtual addresses.

Unfortunately I haven’t had the time to do a proper benchmark, and the fpng test executable only decodes/encodes a single image which produces very noisy/inconclusive results. However, I’m under the impression that it doesn’t make a large difference in terms of overall time.
fpnge (which I wasn’t aware of until now) appears to already be using a very similar (identical?) algorithm, so I suspect the relative performance of fpng and fpnge would not be significantly impacted by this change.
