Re: [tor-talk] Tor relay on small and cheap devices

Cheap embedded systems... low on sources and highly repeatable, yes.
If it's wifi, you could tcpdump every packet received since the interfaces
come up into rc4 or sha until sufficient initial seeding, combine with delaying
login/transit till then, regenning keys, etc.
Worst case is so long as you have and make use of a clock that keeps
proper time across reboots you should never have the same entropy...
predictable, yes; the same on the same device, no.
Some systems save a pile of the last good entropy across reboots and
use that to seed the machine on the next boot. If you don't mind the writes
to flash for that.
