Sure, that wasn't rust's main goal. I did the app in rust simply because I had time to do that and wanted to get more comfortable with lifetimes. (they're in my nightmares now)

But honestly, I came away surprised how good the experience was. I wouldn't start a big team project in it (at least not until more common middleware is available and some higher level frameworks), but when rust 1.1, or 1.2 lands I'll definitely consider it for http microservices or RPC endpoints.
