Telemetry is just in the process of getting going. The capabilities you talk about are coming within the next couple weeks to Telemetry (I'm one of the two lone programmers behind Telemetry). Right now the app is uber geeky but we've made a killer real time HTML5 and native visualization engine with real time push. We're working on making things less geeky as we go but we currently have a native OSX app. Our iPad/iPhone app is coming in a couple weeks.
