Fair enough. It actually reminds me of this push-to-talk cell networks that I first saw advertised 15 years ago: http://en.wikipedia.org/wiki/Mike_(cellular_network) http://en.wikipedia.org/wiki/Mike_(cellular_network) That technology definitely struck a chord with a niche audience. I think the product's name of MiKE was chosen to appeal to male-dominated industries such as construction where it essentially functioned as a walkie talkie with unlimited range.
