Sort of. The worm would still be subject to connection rate and
bandwidth throttling, so the laptops are not _that_ useful as a DDoS
launchpad. But it's all a big hypothetical scenario, because finding
invariants to infect across all OLPC systems is likely to prove
extremely difficult; only applications that the user sometimes runs
generally listen on a port and act as a server. There aren't going to be
unprotected, constantly-running servers to exploit.
