You CAN use electronic dead bolts, but they're expensive, require battery power in the door and are prone to security issues as many of them have reset buttons that are too accessible from the outside.
I think this would likely be better for your application:http://www.amazon.com/gp/product/B000RKVVGU/ref=s9_bbs_gw_d0_ir01?pf_rd_m=ATVPDKIKX0DER&pf_rd_s=center-2&pf_rd_r=1BNVP2ZHEV7WZC458GK9&pf_rd_t=101&pf_rd_p=470938631&pf_rd_i=507846
They're cheap, run on DC power (check the reviews for info on current requirements) and in case of power failure, act as a normal strike.
For the remote control, I suggest xbees or similar to control them. A different way that would cost less would be to actuate the locks via X10 home automation units. A central computer can easily open the doors without using xbees.
If you DO go the xbee route, take a look at the sparkfun serial thermal printer that came out last week. Cheap way to add an audit trail on a central controller
