It appears there is a lightweight web server built into the Roku, because the developer page runs off of this.
It would be useful, to at least some programs, to be able to serve pages out via this web server. I'm mainly thinking in terms of simple form pages to get information from the user via computer or mobile device. These simple forms could then save the results to a local file or the registry to be accessed by BrightScript. I realize all of this can be done by setting up an external server, but it would simplify things quite a bit to be able to do it all locally.
Trying to keep the idea fairly open right now. Maybe the page is only accessible while the channel is open? Perhaps some BrightScript code is required to make it available? Maybe it is accessible via
