so a client has asked me to produce a system for there event that allows the attendee's to send text messages, or face book messages to a screen that can be seen by everyone. I found this http://www.iwall.com.ar/index.en.html but it seems really out of date. the phone compatibilty list is for really old phones, I keep thinking there must be something out there for an Iphone..? anyone have any idea's? the client is really open to new idea's so any suggestions would be great.
