I will agree with what's above and add...
It looks like you're considering an all 1 in solution? I do like the sound of that idea, but at the same time I'm also a fan of backups. If my com goes down maybe I have a
cue light, a walkie, a wired backup to my wireless? Having other options always gives me that warm fuzzy feeling of a security blanket.
There are also a lot of solutions that exist in regards to the questions you're asking. Are you making something new, or making a better mousetrap? Granted I'm a little outside of the norm because I'm picky and I have my favorites, so I have my own
clear com belt pack, I have a "surveillance" style com
headset, single ear lightweight and a double muff heavy noise suppression
headset (surprisingly handy). One of my absolute favorite tools I collected from the film production world is a box that combines my clearcom feed and my walkie, it's an extra piece on my belt, but it is 110% worth it. I find cueing solutions to be specific applications like
cue lights, IFTT automation programming, but again these are all solutions that exist.
I've been working with a production group recently where we're trying to do similar "team" based communication and in that case I can see it being useful, but there's also a reason why there are standards and go to's. It's a pretty hefty task to challenge the likes of
Clear-Com,
Telex and Motorola,
Drop Box and Google which all have pieces of the answers you're looking to question, but if you can make a better
mouse trap (read communication tool) you might have a chance.
