Hey the UBW32 (http://www.schmalzhaus.com/UBW32/) has enough I/O (78) pins to be able to flash LPC/FWH chips in programming mode or A/A Mux mode. In this mode you are able to flash in 8bit bytes instead of 4bit nibbles. A few of the datasheets I have seen says in this mode a 256K chip could be flashed in approx 20us. That is friggin fast!!! The only thing that would some what slow it down is USB. But, the UBW32 is detected as a USB HID device and you can do data transfers over serial console. I think this is a major discovery I will be looking into. Thoughts? Comments?
FWI the UBW32 dev board from SparFun is $40 and has a built in 3.3v voltage regulator, mount it on a daughter board with a socket you would have a smoking fast programmer for about $50 :-)

Correction: "Byte-Program time of 20μsec" "The entire memory can be erased and programmed byte-by-byte typically in 4 seconds"
But that is still really fast!
