You can do stuff in JS really easily with [ports](http://elm-lang.org/learn/Ports.elm).

The TodoMVC example in Elm does this to use localStorage: https://github.com/evancz/elm-todomvc/blob/master/Todo.elm#L... and https://github.com/evancz/elm-todomvc/blob/master/index.html...

The same can be done for HTTP or WebSockets if you have needs that are not met by the existing APIs. Furthermore, the next major release is focused on drastically improving these APIs.

So there's a safety valve right now and there's a plan of how to make things excellent. I would not block on this, but I am also relatively biased :)
