I sometimes used this method e.g. to communicate between a bootloader and an application and vice versa! I's a simple method and takes no additional special hardware! The only thing to find is a RAM area (some bytes) which isn't affected by e.g. the startup-code. Some microcontrollers even have a seperated RAM area which is small and difficult to use as "common application RAM space".
