magoldfish asks: "Our company has several terabytes of data, typically chunked into 2-6 GB files, that we need to share among users at sites around the US. Our users range in technical skill from novice to guru, data access needs to be secure, and we require client access from multiple platforms (Linux, Mac, and Windows). These files will likely be accessed infrequently, and cached on local hard drives by our power users. We've been running WebDAV, primarily to accommodate non-savvy users and guarantee access from firewalled environments, but the users are really complaining about download speed — maybe 50 KB/sec serving from a Mac. Any suggestions for better alternatives, or comments on the pros and cons of alternative access techniques?"
