Stream and roamio plus?

I've had a premiere with a separate stream box from the very first day the stream was available. About a year ago, we replaced our older s3 with a roamio plus. Both have been humming along nicely. Today I was doing some rearranging and realized that the roamio plus can act as a stream for the premiere (they are networked via moca adapters). Sorry if this sounds like a dumb question that I've overlooked for a year, but I dont need the separate stream box anymore, do I?



If my wife wants to download to her iPhone at the same time I want to download to my iPad, can the roamio plus handle that? Or should I leave the 2nd stream box active and dedicate it to the premiere?



Thanks.
