A trade option should be available:

A connects to B:

A -> B: Do you have FOO?
B -> A: I have FOO chunks 011.
B -> A: Do you have BAR?
A -> B: I have BAR chunks 101.
A -> B: I want FOO chunk 2.
B -> A: You are queued.
B -> A: I want BAR chunk 1.
A -> B: Lets trade.
B -> A: Ok.

A -> B: 1K data
B -> A: 1K data
A -> B: 1K data
B -> A: 1K data

Clients that want to trade should get a slot before any non trading
client.

Trading should not be forced to equal speeds but the speed should be
watched. Otherwise everyone would say trade, send a few K data and
then stop sending.

Even more complex could be a extension that specifies a up/down
ratio.

... as above
B -> A: You are queued.
B -> A: I want BAR chunk 1.
A -> B: Lets trade. I give you 1K BAR for each 10K FOO.
B -> A: OK.

I think that would lead to chaos. A lot of clients would try to grab
the chunk and never get it 100% (so they can send it on) and there
won't be any slots left for you to get it yourself.

Only time that would work is if the sharing client is online at times
you are not and you would need an intermittend place that online both
times. Do you run mldonkey only parttime?
