I personally would not ask you to expedite all the way when directly underneath/on top of another aircraft. I work in london TMA and generally ask only for expidition thru a level before the cleared level in these circumstances. I'm sure most of my colleagues are the same. My feeling is that some controllers use the term far too often when it is completely unnecessary. When controllers use expedite in every second transmission I feel that they reduce the effectiveness when thay really do need it. A pilot on frequency hearing expedite every two mins may start to doubt how much control the controller actually has, i know I would!

IMHO, "expedite" instructions should include the reason for the expedition.
"Maintain 3000, expedite through 5000, traffic holding at *wherever* at 6000........."

I rarely use expedite climb or descent. But in any case I do mean the best you can give me. And it is in your benefit because it is then always for seperation. However when a pilot reads back "Roger expediting" I still have no clue on his ROC or ROD as it is not clear at the time what the expedite really is that the aircraft can do or what the pilot is willing to do. So basically I still am not 100% sure this way if I can guarantee separation. Better would be ofcourse to give a specific rate, just a shame if it turned out the pilot could do better.
As well the perception of an expedite climb or descent from a pilot's point of view vary a lot. Sometimes when I give to the same company, same path, same aircraft type a ROD of 1500' or more one pilot will come back as if it would be a low ROD and another pilot will readback; Expediting!
In other words I try not to use it, but when I do I suggest you go down like a brick or climb like a rocket

I've seen various rates from 6500 fpm from a 767 to 1000 fpm for a TU154, which nearly got my fingers burnt and would never attempt again by the way!
Expedite can never be used to ensure separation and in my opinion should only be used as a last resort if headings aren't going to work.
The best phraseology I have heard from a TC controller is "wop on up", not exactly standard.

Never climb an A340 straight to it's requested level; use as many IFL's as you can. Specially in the summer period. During winter periods ons sometimes can have the luxury to skip an IFL.

My experience using a location or time as a condition to a descent doesn't always work with some companies from a particular region. And then to use it for separation can be tricky.

Heard this while eavesdropping on Vilnius APP some time last year.
Scenario: Formation of 2 F-16s in radar trail inbound Vilnius for a practice approach, passing FL200-ish.
Vilnius approach: "MA01 flight, expedite decendt to alt. 4000ft"
A/C: "Wilco, MA01"
50-ish seconds later......
A/C: "MA01 4000ft maintaining"
Solved the first conflict beautifully, but they did plummet past another a/c!
Never use it unless you know what to expect!
Made a dreary day as liason in Siauliai tower a bit more fun
