/dev/urandom on linux and openbsd will not block; they just print hashed versions of what is in the entropy pool. /dev/random on linux, and /dev/srandom on openbsd will block until entropy is available.

Robert M Love has put together some patches for the Linux kernel to add network interfaces to the device drivers that generate entropy for the random pool: http://www.tech9.net/rml/linux/ Note that this is of debatable value; since network traffic may be seen or even controlled by attackers, it may or may not add real entropy to the pool. You need to decide for yourself if this is a concern.
