A few years back there was a kickstarter for a company called Hop Theory that was trying to sell hops in tea bags you would put in a glass of beer.

I'm thinking it could actually work if you brewed a light lager for the summer and didn't have room for a keg of hoppy beer. But instead of putting a single pellet in a glass, I'd get a kitchen canister that a had a lid that sealed like a big Grolsch bottle, fill it almost all the way with beer and add the hops, orange peel and coriander in a metal tea ball. Close it up and keep it cold for about a half hour and see what happens. You'd lose some carbonation, but not all.
If you wanted to be thrifty, you could even save the hops, since they haven't been boiled, and toss them in your next brew. I have some lager on tap, and my keg of IPL just kicked so I might try it later today.
