How about an online service such as a VPN? Or other monthly subscription service that would attract customers, preferably crypto ones.
I like this idea but wouldn't it still cost money to set up? I think like mentioned before it is a problem that the coins are just received and then sold immediately. I think the biggest problem with devcoin is that there really is not a ton of people accepting the coins.
You'd need a lot of bandwidth and an IP address you wouldn't mind getting blocked. (Most VPNs end up getting a range of IPs they use blocked due to spam, etc.)
