It means what it sounds like: coins are addressed to hashes (double SHA-256 hashes?) of X-coin scripts instead of X-coin addresses.
A miner could also regulate the number of outputs he or she permits a transaction to have.
The latter point is of course true, and I fully expect that data transactions will pay their fair portion in miners fees to be seen as worthwhile from a miner's perspective. It is after all only fair.
As to the former point though, I still don't really know what you are saying. Also, I really do want to know what a Great Empire Coin is.
1. An X-coin transaction that is addressed to an X-coin address contains an X-coin "script" which includes the actual address and some related commands. An X-coin transaction that is addressed to an X-coin "script hash" contains an X-coin "script" which includes the message digest of the aforementioned kind of script and some related commands.
2. Great Empire Coin (GEC) is the official currency of
Great Empire of Earth in much the same way the United States dollar (USD) is the official currency of the
United States of America.
