Are there any pros/cons of the built-in streaming capability of the Roamio Plus/Pro models vs the standalone Stream box? Are the Roamio Plus/Pro models possibly using newer chipsets that could be better? I believe that they got OOH streaming functionality first, so is there any reason to think that a Roamio Plus will be more "future-proof" in terms of getting streaming updates/fixes/improvements compared to a basic Roamio w/separate Stream box? I've also heard that the Stream has a fan, and some have complained about it making a whine. I'm assuming the Roamio Plus also has a fan. Might one setup be quieter and/or run cooler than the other? I'm throwing all of this out there because I'm contemplating switching back to TiVo (been using WMC for a while now) and need to serve two rooms, plus would like iOS streaming capability. So I'm debating between a Roamio Plus and Mini or possibly two basic Roamio's and a Stream.
