Cutting JTAG pins of the chip if they are not used may be a temporary solution ;-)

indeed this restrain LPC2000 use so far only for LED blink projects :)
nobody would consider to do something serious without copy protection
anyway it's still great chip for beginners who want to learn ARM
architecture
there seems to be a bugs in the silicon too, but hopefully this all
will be improved, LPC2000 is quite inmature chip after all

I have my eye on OKI chips:
http://www.open-research.org.uk/ARMuC/index.cgi?ML67Qxxxx
according to this web price range is $6-$10 and:
http://www2.okisemi.com/us/docs/MCUTables-9.html
ML67Q5003 seems perfect replacement for LPC2000 with it's 512K Flash
32K RAM 60Mhz ADC, I2C, UARTs etc.
