Try before you buy?

So, I've been a part of the audiophile community for a long, long time now. A major part of the hobby, IMHO, has been gear rolling: trying new stuff, deciding if you like it, and then moving on to the next thing. Cable rolling is probably second only to tube rolling.
When I was at MIT all those years ago, I decided the industry really needed a true lending library. So, I've been building one and have had huge support from cable companies like MIT and Cardas. It's good for them to let people try their cables out to see how much they like them, if at all. Consumers who really fall in love with a pair of cables will eventually buy, either on the used market here on AudiogoN, or on the new market through authorized resellers.
Anyway, I wondered how many of you would use such a library, and, if so, how you think it might change the way you buy audio gear (if at all). I'd love your feedback.
