Thanks for the help here! I tested some of these out on my recent iPad, iPhone 4 and HTC Android
junaio://channels/ is the only thing I've found that works with iPad, iPhone 4 to bring the APP junaio back with the same channel loaded (also will launch the application but not to a specific channel obviously). It does not however refresh which would be nice for what I wanted to.
junaio://channels/?id=XXXXXXX junaio brought back APP junaio but with incomplete model loading
variations of these on the HTC Android will launch and bring back junaio but not to a specific channel.
URL Linking to your particular Channel I have found with AR is super important to getting people to where you want to go fast without too many steps. If a user does not have junaio installed then a prompt at this point is also important. It will be great when this works for both IOS and android. But imagine I am preaching to the crowd!
