I'm old enough to wait until a technology has somewhat proven itself before jumping on it for client work, personal / internal projects are the perfect place to try this sort of thing out though and get a feel for whether you think it can succeed. I've had a pretty minimal play with Phoenix and I liked what I saw in terms of developer productivity and application performance, things looked a bit less certain when it came to CI and deployment though. This was a while back mind, and these areas may have improved a lot since then.
