The DirecTV distributed client/server architecture of a mixed DVR and non-DVR environment can be a nicely designed and very flexible architecture for both homogeneous and heterogeneous households.
For those with simple setups, a single DVR with clients may be perfect.
For more tuners/redundancy/functionality(pause, DP, ...), add another DVR.
For those with different preference groups, assign one DVR per group, or more then one if backup is required.
Meanwhile, if desired, every recording can be seen by every receiver/DVR, no matter the complexity.
Overall, a perfect client/server architecture.
The only deficiency (personal opinion) is the lack of ability to specify a single or subset group of DVRs from a remote site, then it would be truly perfect and flexible for most every possibility, including the most complex. Personally, just single DVR selection is needed here, but do understand that others may have more complex desires. And then there's always the discussion of personal Playlists.
For this household, the architecture is one DVR per major viewing location and/or heterogeneous group (total of 4), and then one non-DVR for each casual viewing location (total of 3). Spread very nicely, and with some redundancy as well.
