I might as well weigh in on this...

I certainly don't want/need the code to be perfect. My main concern
though is that I have seen problems with xmac and lpp. The mc13224v
uses DMA to transmit and receive bytes and I'm worried that there are
concurrency assumptions in Contiki that get violated when the radio
driver returns right away before any of the bytes have been
transmitted. Unfortunately though, I don't know much about how contiki
is suppose to work and so it's difficult for me to say whether "it's
good enough" or not. But then again, if a contiki maintainer wants to
pull the code in as-is I won't stop them!

Regarding the synchronization issue, I'm doing much better now. At the
moment we are only one day behind.
