*JUST BECAUSE* thats how it was done in 48 hours does not mean the stargate cannot be reconfigured. There IS a buffer there built into the stargate to hold the matter stream. That means with some tinkering / reprogramming, the stargate can be instructed to do things differently - taking the matter through the demolecularisation process and storing it in the buffer as normal but NOT sending it.
A bit like when you send an email in outlook but you go into the options and change then to "Do not deliver before xxxxx". Next you'll be telling me that Outlook (with MS Exchange) doesn't do that...
The point is, Destiny is not a normal ship. It's gate it not a normal gate, they are hooked up together. Destiny can communicate with many stargates directly (so far the only ship we know that can do this) and its stargate has two programming consoles in the gate room.
Why can't you get used to this idea?
