Can airplanes transmit/relay flight data to ATC's periodically while in flight?
Large expanses of Australia and Hudson Bay in Canada, currently without any radar coverage, are now visible on ATC screens after strategic placement of low-cost ADS-B receiving stations
Inmarsat has confirmed it has proposed to ICAO a free global airline tracking service over the Inmarsat network, as part of the anticipated adoption of further aviation safety service measures by the world’s airlines following the loss of flight MH370.

The flight data recorder is one important piece of information in the event of a crash. Can this information not be transmitted or relayed to the ATC's while the flight is air borne
That would be inappropriate, ATC have no interest in or use for such data. It would be better for the data to be transmitted to the aircraft operator under rules set by a regulatory authority.
Live-streaming of flight data has been proposed by IATA and has been investigated by the NTSB amongst others.
The U.S. National Transportation Safety Board (NTSB) has said it was studying the possibility of live-streaming data, but Tyler said a broad consensus would be needed between airlines, major manufacturers and regulators.
"It's very important that if we're going to have regulation covering this area, that it's done on a globally consistent basis,'' said Tyler, who joined IATA in 2011 after five years as chief executive of Cathay Pacific Airways.
