One stream at a time means only single young adults will be interested in this service.  IF they made it like Netflix with more than one stream available at a time, then I would say it could work for older adults that are married or retired couples etc.  But from what I keep reading they only want  is it 5million subs period to take the service . If more people subscribe than that ,  then ESPN can drop out of the contract and there goes their hook to attract young single adults all over again.  So I don't see how this will work in its present form, before they will need to  change the way they repackage it to sustain it for the long run.
