Lpc2000

I don't believe I did misinterpret what the original poster said: 
they expressed a concern that units in the field could potentially be 
left in a state that is unrecoverable without manual intervention. 

Whether you know what you're doing or not is immaterial when doing 
something like patching a boot loader: it's relying on undocumented 
and unsupported features. I'm happy to stand over my contention that 
this is a poor strategy for anyone putting product into the field, 
regardless of whether it works.

You are of course entitled to disagree with this, and to advise 
others as you see fit.
