There are now a number of tournament manager applications on the iPhone. Some of them are getting very nice, and innovative. One particular one is called PokerBuddy and has a feature that let's other iPhones connect to the master time keeping app and mirror the information. This is a great capability for when a tournament spans multiple rooms in a home, or when some tables don't have visibility of the timer.
So, that leads me to my feature requests:
1 - a way to mirror key tourney information on iPhones or iPod touchesl (VNC is too complicated for the average player)
2 - a way to remotely record knockouts, pause the time, etc from an iPhone with "admin" privileges -- since at our tournament for example the admin is also playing, it would also be useful to allow more than one person with an iPhone access privileges to do so.
