Access to underlying APIs

Having played around with the NodeJS SDK I bit and just having run the samples of the C# SDK, I feel like there's a case to be made for exposing the underlying connections to developers.

E.g. setting up the NOdeJS SDK involves it making a lot of requests - requests that may not always be necessary. E.g. if you don't care about processing instant messages / presence states, there's no need for an active XMPP connection. Also, starting the NodeJS SDK seems to fetch a lot of data which may not be helpful to the application you're developing - thus only eating up resources and slowing things down.

I therefore feel like it would be useful to be able to access additional REST endpoints and the XMPP interface, so that we have a choice to use only what we need and only set up connections that our applications need.
