*Wildfire* was quite the system back in the 90s, seems like the Android Dialer or Google Voice could easily implement the best features today.
Some tidbits:
- When summoned Wildfire says "I'm here"
- Whispering in your ear could be done on phone, but also in real life if you had, say Google Glass.

_For now, Wildfire is only for those willing to shell out big bucks. A business with a dedicated server pays an average of ,400 per user to get set up. Independent subscribers who buy the service from authorized service providers generally pay monthly charges of between 50 and 00. Lowering prices is the company's top priority. Competition is looming, but to date no one else has as sophisticated a product on the market._
