My first instinct was to try to solve this from the other direction.
Can ::Server be modified to allow streaming?

Streaming is usually used for large files, the kind you may not want 
to try to fit all in memory at once.

On the other hand, your approach could also be considered reasonable.
If the user has requested the "return only" behavior through the
environment, shouldn't the Stream plugin comply?

I'm interested in the opinions of others as well.
