Since Android devices are often hidden behind firewalls and NAT devices, it's not possible to create a connection directly from an FTP client to an Android device. Therefore, I maintain some proxy servers that help circumvent these limitations. Traffic can be routed through these proxy servers, which solves the firewall problem, but these proxy servers aren't free.
I (Dave) am a graduate student with a limited budget. I'm interested in developing cool distributed applications like the SwiFTP proxy, but I can't afford to subsidize everyone's bandwidth. The proxy servers cost me about $50-100 per month each to operate.
So I'd greatly appreciate some financial support so I can afford to keep the proxy servers running. I suggest about 30 cents per gigabyte if you use the proxies frequently, but I'll be happy to receive any amount greater than 0.

If you're interested in the proxy design, check out the SVN repository. In particular, look at "proxy_design.pdf" in the cloud_server directory.
