I wrote a kernel module for a S1 a while back that monitored all disk 
reads/writes and optionally streamed them out over UDP (cachecard "burst 
mode").

If you know the sector range of the ring buffer it would be possible to 
tell the kernel module to automatically stream out all data written 
within that range.

The speed is fast as it doesn't go through the TiVo's network stack - 
the code bounced the hard drive data directly to the network card driver 
in kernel space.

Could be interesting for a DirectTV S1. The quality of a SA S1 is pretty 
bad.
