> Also -- supposing that this business model was completely viable from a security perspective -- the next step to building such a system might be to build an auction site for CPU cycles (or compute ability/compute time) -- sort of like an "EBay for highly distributed but sandboxed code execution" (clients bid on renting compute resources, end users bid on selling theirs) which would be an interesting business model, IMHO... In Commonwealth saga from Peter F. Hamilton, people have access to nearby computing nodes like we have currently to free wifi, for accelerating any tasks they would need (like personal assistants, called e-butlers). That's not 100% secure and is sometimes used for nefarious purposes (and plot devices), but it's just accepted as a nuisance like other things that can be weaponised in our own reality (like cars).
