I think we're having a few misunderstandings in this thread. Starting with the original subject "Add live local OTA channels" there is a difference between over-the-air (OTA) broadcast channels and streaming channels (which the OP described as channels which "air over the internet" which is true in one sense but semantically confusing). Yes, some OTA channels also provide a separate stream so a particular channel may be available in both formats. In Roku parlance, "channel" should be thought of as an analog to "app" on a mobile phone, so it is confusing when, unfortunately, the same word means two very different things.
As I understood the OP, the request is for The Roku Channel to support streams that are currently available on other (Roku) channels from other providers. What was requested originally is very unlikely to happen. Since each of the streams may be delivered in a variety of formats (as to user authentication method, data rates, compression, ability to pause, rewind, or forward a (non-live) stream, tags for ad insertion, and so on), the "Roku channel" app can't necessarily know about all the different methods streaming providers may choose to implement a stream.
On many Roku devices, storage can be added via microSD card. And the apps themselves do not take up an inordinate amount of space. Storage is cheap. Coordinating a standard format for different streaming services is as much a business issue as a technical issue. And absent a business model for use of ad inventory, it won't happen at all.
To the OP: the best the friendly community here can offer in this case is a workaround. I'm sorry if my original attempt to be helpful was not received as such.
