The problem with these things is that they are marketed as solutions to "problems", as if conventional techniques were hopelessly flawed or overly complicated. That marketing rhetoric always ruffles the feathers of anyone experienced enough to know better. Unfortunately, it's such a turn off that it breeds a sort of elitism and close-mindedness towards innovation.
Imagine if one of us lab-members discovered this effect, and offered up his/her observations to the people here. What a thread it would be! There would be a group-buy for the ingredients to make the material, and probably numerous externally-linked web pages of "how-to" information. Many of us would be experimenting with the stuff, discovering potential uses, exchanging experiences, etc.
I bet the stuff sounds kinda weird. But I'm sure it has a sound of it's own, which may or may not be interesting. Either way, it appears to be a new thing, which can't be all that bad. I say, ignore the marketing! and think about the possibilities.
Personally, I can't imagine that sampling a vibration without having the interaction with air would yield a very realistic sound, but then again, electric guitars sure as hell don't sound "realistic", and we'd probably hate them if they did! Who knows, maybe these things will distort in insane ways which will inspire some new kind of drumming! Seriously, what would Jimi Hendrix have sounded like if he only had access to a strictly realistic amplifier???
Maybe I'm hopelessly optimistic.
