Answer to the original question:
No, putting recco on your gear is extremely irresponsible. If there is a rescue situation there is the potential that your ski would be dug up before a person. (this is the same argument made against putting a beacon on your dog) Please do not do it, you are putting innocent lives at unneeded risk (i.e. the guy beside you skiing with recco on him).
Anderson.$ Said: "once they find a lone ski they will have little energy left and you wont much/any oxygen left."
Not true, the person buried would have plenty of oxygen left. Avalanche victims don't die from lack of oxygen. But your spot on, time is the enemy and finding a ski before a person could be devastating.

Not an engineer here but the idea seems valid but I doubt it will happen. I know companies like sos and ortovox make a special dog beacon that is on a difference frequency, but obviously that wouldn't work for gear recovery. Since recco is a reflector system its a different idea then simply changing frequency I think. Maybe an engineer can talk about it. But I doubt there would be money to fund a "gear recovery" device, its simply too small a problem.

The system has proven to be effective in Europe with numerous live recoveries. However, here in north america our rescue setup is a little different but there is definitely a possibility of a potential success story. One of the benefits that is often overlooked with Recco is that you can use it from a helicopter flying over large debris fields, something you can't do with beacons. But your right in that its not something to relie on, but neither is any piece of rescue gear.

The recco system is NOT meant to replace an avalanche beacon. The recco system is NOT designed for backcountry travelers. Read up on it more at their site. Please do not think that by having recco you are safe to travel out of bounds.
My personal thoughts on Recco:
Great idea (although I still ski with my beacon in bounds). Will become more effective as the technology improves and more resorts hop on and more people have the reflectors. One interesting thing to note is that they used to sell Recco reflectors individually with a sticky back so you could put it on your boots etc. but because of people doing this exact thing (putting the reflector on skis to locate it) they stopped doing this.
I have used the system a fair amount (although never in a real scenario) but am by no means an expert. Read up on it at: http://recco.com/startsida/index.asp
