Hi Walt,
I think that ARTX is now called RL-ARM (Realtime Library ARM)
https://www.keil.com/arm/rl-arm/ . It is a low level RTOS with support for the USB / Ethernet as implemented e.g. on the NXP devices.
The footprint / memory requirement is minimal and the learning curve should not be any issue.
In circuit emulators are still something you might consider as there is a trace interface on most LPC2000 devices that would enable real-time trace with emulators from Lauterbach, Hitex, Nohau, Signum, iSystems... that all support the LPC2000 chips.
The embedded debuggers from Keil (uVision with U-Link) and IAR (C-Spy with J-Link) have similar functionality.
Pro Keil: a simulator that can simulate all peripherals and provides debugging that is very similar to debugging in SRAM. That enables a trace feature as well!
Pro IAR: There is an option with J-Link to put breakpoints into Flash "Flash-Breakpoints" those come in handy as otherwise you are limited to 2 hardware breakpoints supported by the ARM7 architecture. That is good enough for single stepping and one more breakpoint and can be a pain..
J-Link can download faster into flash.
Both companies offer trial version for download to get familiar with their IDEs. What about giving both of them a 4h window and check which one you like better / which one gets you going faster.
