I've been pondering starting a cheap service that accepts bitcoin (too cheap for CCs and not worth the hassle of paypal), but wasn't sure about the viability of relying on bitcoin as the primary transaction currency.
Bitcoin transactions in testing have worked perfectly & the display is zero conf which means you can pay and see that the payment on the hash the minute.
Customer uptake has been lacking for my project, but I believe that's because I've created something that works really well for two very niche markets (which fortunately have a lot of overlap.) depending on what your project is, you can always add a credit system whereby people can dump $5 or something via credit card and you allocate that to them for them to spend as and when they need.
You have my thanks!
A note on ipfsstore: while ipfsstore provides a very valuable service for those who know why such a a service would be used, the website provides no real information for those who don't already have that prior knowledge. What little information it has is tucked away on a separate page. I think if you clearly advertised the primary value that your service provides (offsite data redundancy/replication) on your landing page, you might see more uptake.
If IPFS and bitcoin ever hit critical mass, I think you'll end up with a surprisingly lucrative venture on your hands.
