Intelligent NIC downloads while host PC sleeps

"According to the team of six researchers, who are reportedly scheduled to present Somniloquy research and prototypes at next month's USENIX Symposium on Networked Systems Design and Implementation in San Diego, 67 percent of enterprise desktop PCs remain powered on outside work hours, and the average residential computer is on approximately 34 percent of the time. Enterprise PCs are often left on for remote access, while home PCs are left on for quick availability, file sharing/downloading, instant messaging, and email, the researchers say.

"As developer Yuvraj Agarwal and his colleagues point out, most desktops and laptops commonly feature an energy-saving S3 "sleep" (suspend-to-RAM) mode, but they cannot respond to remote network events while they are in this state. And, while WOL (wake-on-LAN) technology has been touted as one solution to this problem, it typically does not work remotely because of firewalls, because of the need to know in advance when a system is sleeping, and because of the need to know the MAC address of the sleeping PC."
