Hi Randy! I was looking the RFA1 for quite some time now, and it is a very very nice chip (under 6 USD at 100 pieces). I would like to put together a test environment / cheap mote, but probably I need help from people with PCB design experience. As for tinyos support: the MCU would be fairly easy to support. The radio chip is indeed very similar to the RF231, however all accesses are down with direct register read/write instead of the SPI bus. This would make this chip very fast and efficient for low power communication. The port of the RF230 radio driver to the RFA1 should not take more work than a couple of weeks. The longer term question would be how to best utilize new functionality (MAC timers, encryption).
So if you are thinking of designing a cheap, small form factor RFA1 based mote, then drop me a line.
