Trading a military unit

[Colossian]

I founded a new city in 4000BC. Unfortunately I didn't have any bonuses. My rivals took a high score. I saw the awfull messages on my screen. "Your rival built Stonehenge, Oracle, Pyramide, Great peoples and etc.

I thought I were screwed. Suddenly I started thinking about.....
"Could I trade my dozen of military units for a tech or gold?"

MP is possible. I can chat with my rivals about these radical trade. First, Open boder and I gift my units to the rivals, after that contact them to get something.
SP, on diplomacy screen I couldn't find "Available units : warrior(10), archer(20), ......."

Is it good?

Nope you can't trade units with the AI. You can only give them away.

Units at present can only be gifted, though this is an interesting idea - there are a couple of problems with it that I can see though. Firstly, it would be hard (but not impossible) to make the AI calculate the worth of units hen you consider maintenance costs and the fact that the context is so important, including the unit's location. Secondly, you would need to either let the player select which units were traded, which is slow and tedious, or have to be extremely careful about your units' locations. in the former case there would also be diplomatic concerns regarding third parties - if I gift or trade a few advanced units to a civ for use in a war against a third player, there ought to be a diplomatic penalty with that third party if they're aware of the trade.

There should also be a penalty if that AI back-stabs you and uses those units against you. Kinda like a nationality penalty. Penalty could be removed if the unit is upgraded, so trading off your obsolete units do not become a permanent shield.

(wishfull thinking)
Trade/sell available if the unit is in the other players territory.
Universal trade cost: Value of the unit is equal to the upgrade cost.
Trade rejected if target AI does not have the gold to buy it, or if support would cause too much of a drain. (IE: AI civ at -10 gpt)
You can only sell obsolete units.
