The thing is, there are no released libraries for writing to the Esplora display (yet). So a third-party solution would have to have a fairly well documented library available for testing. If your display has such then it may work. I made the connection with the Adafruit display as the pinout is nearly identical and Adafruit publishes a fairly good library that could be changed if necessary.
EDIT May 17, 2013 - see http://www.arduino.cc/en/Main/GTFT on libraries etc. for the now announced official display
