Why are P2P Companies Seeming to Fail?

After reading "Is P2P plunging off the deep end?", which claims that P2P may be more of a passing fad than a legitimate new business niche, I had a thought. P2P is only in it's infancy and hasn't gotten much of a chance for the natural development of technologies. Up to now there hasn't been much more than hype and Napster. P2P companies seem to be running into a similar problem that the dot-coms did: oversaturation of an overhyped technology results in a thinning of the market. Only in the case of P2P, there isn't a market to take advantage of yet.

Yes, P2P may become the redefinition of the web, but we're not to that stage yet. Have P2P companies become overly-eager, not seeing that we're not close to the place that we would like to be? P2P outside of Napster is still relatively for techies only; there needs to be a reason for Joe and Josephine Public to use it. Sure, file-sharing is neat, but why would they care about distributed computation? P2P can only prove its worth if adopted and accepted by the general public. Because of this, P2P companies are failing because they are getting into the market too early. Ask Popular Power, whose CEO Marc Hedlund said "as the market has gotten tighter, it's been harder to raise angel funding." Investors are taking a wait and see approach, while P2P companies are taking the stance of "if we build it, they will come". Well, the paths to P2P bliss aren't there yet fellas, but keep building them, we'll get there eventually, it'll just take some more time.
