Not sure if this startup is only doing 1-to-1 or it's 1-to-n, but if they start allowing 1-to-n, they'll likely run into problems. A walkie-talkie system will likely fail for larger group sizes (e.g. >8) or more due to cross talk that will build up on a common channel. In the marine environment where ‘walkie-talkies’ are still in use, folks have worked around the problem by monitoring the common channel, 16, for interruption and then negotiate a switch to a less common channel to complete the conversation. In the long run, maritime folks will likely switch to TCP/IP to address, route and communicate more efficiently rather than the walkie-talkie system. This sort of thing crops up in the office when a scrum master says to take it 'offline' in a standup, or when an open office gets big enough to have a din of conversations all going on at once.
