Hi Tom,
the only option to get J-Trace a little cheaper would be from the
source: http://www.segger-us.com/jtraceusbtotrace.htm , although it
seems to be out of stock right now.

Just down load the spec from ARM and do your own hardware. It's that
simple. Of course it will cost you a LOT more than 1300 USD to do
You could of course hire some one to do one for you but that will cost a
LOT more than 1300 USD
You could as Lauterbach or iSystem for their ARM JTAG-Trace systems but
they are a LOT more than 1300 USD.
AFAIK even if there is a published circuit for an ARM Trace system it
will cost you more than 1300 USD to make one.
The least expensive answer IS the IAR J-trace.
If you need trace the amount of time it will save you (and Time ==
money) the IAR J-trace is cost effective.
BTW how do you have "Open Source" hardware? :-) Who in their right mind
is going to spend a lot of time and effort doing an ARM-Trace system and
make the hardware for less than IAR? They have economy of scale. You
will have to make several thousand off to get the manufacturing costs
down to a similar price.
So the IAR J-link IS cost effective at 1300 USD.
TIME == MONEY
Work out what it costs your company to run you per hour (usually at
least double what they pay you. ) Divide that amount into 1300 and then
see how many hours you have spent looking for a cheaper option, how many
hours it will take you to do your own. I bet you will find buying the
IAR J-trace will be the cheapest option by a long way.

I am using IAR Workbench w/ JLink & have been thinking that Jtrace
capability would be real useful. Unfortunately, JTrace is ~ $1300 for
the hardware. Is there any open source or 3rd party Jtrace hardware
around? I'm using NXP LPC 2300 chips mostly.
Thanks, Tom
