This is a characteristic that we cannot conceive of removing without wiping out the Internet as we know it and introducing a host of new problems more serious than the one remedied.

Protecting a single system against becoming a node for parasitic computing is also fairly difficult, because the number of resources stolen from a system is often a negligible fraction of the idle CPU time and memory and, hence, might easily go unnoticed.

Chances are good that parasitic computing has yet to show its full ...
