Well, I'd love to use that information that you have collected to 
perharps make an open source bootloader for LPC devices.
I think the original one is good, but, there are several things that 
could be improved, like upload of code not plain (so you can distribute 
you update files to the end user), and, a simple timeout would be great 
(if for some reason you start the bootloader, your application is dead 
forever...).
