I am working on a 11K SQ FT home which is using a dozen local processors. The new 9.0 prelim to Apex with Slave/Master processors makes it work fantastic when using multiple local processors. On a large home, one processor is not going to cut it especially if the client has complex local systems with multiple sources. Some people don't want to do video distribution and want ultimate quality and flexibility. If you are not going to use static IP try reserving the MAC address at least. But definitely, definitely set it up as a master processor with underlying slaves.
