Another option you can consider, if you have a bios that is new enough to boot from a USB device, is you could put together a basic Myth system on one of those tiny USB flash drives. Certainly doable on a 1gb drive -- in which case you could not use NFS at all because you could stream the Myth protocol if you use the CVS version without the remote frontend file handle bug, but you could probably fit easily enough in smaller ones. You might want to put some things like /tmp and parts of /var into a ramdisk to avoid constant writing to the flash, which you want to avoid. You could also do boot and root from a much smaller flash card or drive (for $16 you can get an IDE flash adapter that in theory means you don't even need a new bios) and then mount the rest of your filesystems over NFS, including your video spool. What that gets you is something fast, silent and local with no seek times when it comes to running the local programs. No seek times can mean a pretty fast boot and other operations. Considering how cheap a 256mb flash card is today... Though you want one with a good read speed, or on USB one that is usb 2.0. You have an extra "spindle" so that read/writes to your main programs don't take the seek arm away from your video stream. But I haven't tried this to see what you really get. Unlike the noisy boot hard drive, you don't need to spin it down. There is also CD boot, but then you have to swap the boot CD in the drive when you want to put DVDs and CDs in there. You may find it easier to get pxe boot operating and just be all network.
