It looks like the patent covers a specific approach to DRM at the OS level.
In theory, another approach could be for the kernel to relinquish control of certain pages of memory to a user-level app, removing them from the kernel's VM subsystem altogether. The app could manage those pages using direct bios calls. Since the kernel has no access to those pages, other apps running on top of the kernel couldn't acesss them either. The kernel could wipe the pages when the program exits.
It's possible that this a hairbrained idea since I don't know much about kernels other than what I learned in school (CS LaTech 1998) but maybe not.
Also, does anyone else have any ideas about how to implement DRM (or more generally - protected memory) outside of the MS way?
"Personally I'd rather see a standard stereo component sized box, a UI that operates through your television and normal remote, and 30+ gigs, but this one is looking like a great start."
I noticed that in the Oracle and Open Source table of contents, the author has chapters on open source tools for connecting to Oracle for web development. Unfortunately, he didn't include my project: SQL Relay.

SQL Relay is a connection pooling mechanism. The number one problem with using Oracle on the web is the connection cost. SQL Relay solves that problem.

Here are some specs for the ZapStation.

Meeting these specs could prove more challenging than one might think with "cheap PC hardware" and "a little software".
