Has anybody implemented Oracle Lite ? If so, I have few queries :

1. we are desining an application where lot of field engineer are involved. all of them carry a latptop with them. We have a centralized oracle database. Each of the engineer assuming has oracle lite loaded on his machine for day to day transaction and end of the day want to syncronise with the main database. How feasable it is ? How is it done ? In case if I want to store couple of image files also in the oracle lite database..does it support ? any inputs with respect to this problem and oracle lite is highly appreciated.
