I just finished writing exactly this application.
I used the CompactFramework altho its not necesssary (I just wanted a cool
GUI)
Parsing the .bin file is not that bad ... look at the bootloader code.
Its nice if you have enough RAM to totally store a whole new image (may be
upto 32M??)
I used the memorymap file function to overcome the application partition
size limit.
otherwise you have to "chunk it" not that cool if you lose power etc.
