Tracking Places that Accept Alternate Cryptocurrencies for Payment

[EuSouBitcoin]

In the long run, I think a cryptocurrency's success is dependent upon the number places that you can use it as payment. I've seen some lists of where you can use Bitcoin as payment. But are there any lists of where you can use other alternate cryptocurrencies as payment? Or is there a good way to track whether the number of places where you can use alternate cryptocurrencies as payment is growing or shrinking?

IIRC there was someone selling a 5970 for I0coins a while back, but beyond that I know of no shops or individuals taking alt coins.

A few shops currently take Solidcoin:

Arimaa Game Set

Instant Proxy

PyroChem

And a few individuals as well. Other than that, however, it definately doesn't have a massive market.
