Attorney Ronald Kaniuk had a routine foreclosure mediation hearing scheduled in Miami on behalf of his defendant client. The problem was his office is in Boca Raton, Fla., and he would have spent much of his day on the road, waiting or sitting in court for a five-minute hearing.

Kaniuk turned to Jonathan Broder, who recently started MyMotionCalendar.com, a service that provides law firms with coverage attorneys to parachute in for hearings throughout the state. Kaniuk e-mailed Broder at 5:15 p.m. for a hearing the next morning.
