That's somewhat intriguing.  It's the first I've heard of any hint at all 
that the parts can be programmed via a parallel programming algorithm 
rather than only via JTAG and serial port.  In fact given what has been 
revealed of the internals I would have said it was unlikely to be 
possible.  Have you any Philips references?  I can find no mention on their 
web site, indeed the closest I could find was a table that indicated that 
parallel programming was not an option for any of the LPC family.
