Adhere to the full Streams API about send HOT 4 OPEN

FWIW I feel like the current API is pretty janky so totally open to an API that flows better, especially the output side. Many would like to see this write to a transform stream to do transformations, which sounds like you're ask too.

Yea, definitely would like to see. Node.js 0.8 will be dropped with the next major but 0.10 support won't be removed anytime soon, so if it's possible to still support 0.10 that would be super awesome.

In addition for Node.js versions, everything in this org tries to support as many Node.js versions as possible -- it's part of our philosophy. We have the ideal support line (down to 0.10 currently) and the hard line of must go down to at least (4.0 currently). Really the minimum version is negotiable between those two, and if 0.10 isn't picked there should be some good reasons to why it's impossible to support lower (in the past we have used compat helps like on-finished to accomplish tasks like this, so perhaps it's just to make a new one).

Yes, I need to apply a transform afterwards (compression).

I'll see what I can come up with, I'll target Node 4, and then we can see if we can stretch it to 0.10.

I'm in your same shoes for backward compat, as readable-stream@2 (pulled from Node 8) supports down to Node 0.8.
