Request/suggestion for Simple App: Appointment to SMS

I am looking for a very simple app (might exist?) - when I view/add an appointment on my BB, I would like to be able to click the BB Menu key, and have a "SMS Appointment" option that will copy the basic appointment details (date, time, subject, location, possibly notes)

I know that I can invite an attendee via email, but it is easier/more immediate to let contacts know via sms

Anything like that? Are there any forums/places where people take app suggestions?
