My bad, I misread your initial comment as "it would cost a lot of money"! Memory might be the limiting resource to support time travel debugging in some use cases, but for the ones we are targetting, the problem space is a bit more diverse. When multiple machines and multiple languages are involved, and web services are running online on a distributed compute fleet, the variety of challenges to account for goes beyond the amount of hardware that we can throw at the problem.
