I would assume that after the wallets are all finished that we're going to be looking at a business type-front here soon? Being able to spend SPN will go a long way to boosting its value.
I'm not saying this is a bad idea, but we have to be really careful about this approach. If you just open up a store-front, there will be a lot of selling pressure as those that have mined the coin start buying stuff. See GPUCoin. Once they opened up their store, the price plummeted and never recovered. You need to make sure that you increase the demand, which is not easy to do.
Edit: To increase the value of the coin, you need people not just to buy it but to hold it. If they buy and then spend right away (which most likely means selling as the merchant cashes out), it won't have much effect on the value.
