Just use diskless myth frontends that netboot off the backend.  Then only
one system upgrade to do, and one system disk.  Works great for me.

Only trick is cooking your "update-client-roots" script.

David Brodbeck:

 |powered diskless frontends.  This would maintain the benefits of

 |A fly in the ointment may be HDTV, which genuinely requires a lot of  
 |resources for playback.  

No HD problems here.  I can watch one (prob two) 1920x1080i progs on the
diskless front-ends while recording yet another on the backend.

Each 1920x1080i stream to the clients is only ~2 MB/sec, so if you've
got 100 Mbps ethernet strung around your house, 1 stream only eats around
25% of the total bandwidth.

As far as playback on the clients, the Athlon 64 3500+ CPUs and 
GeForce 6200 LEs with Xv is more than enough to do a perfect job.
