About IR, it is half-duplex commnuication, but it is not a problem when you make a useful protocol.
have a look on the ethernet protocol, the ethernet also support half-duplex, and it have broadcast function.(i means ethernet, not TCP/IP ;-) )

Thanks for the info, we are looking at something like PL2303 which is
having a cost of 1.7rmb / piece according to our supplier on taobao.
15~20 is more than the Atmega we are going to use.

此外另外一个挑战就是群体编程,因为如果我们想做Swarmrobot,一个一个下载程序不现实。目前我的想法是Serial over IR, 直接用一个455kHz的红外接收调制过的串口信号,但是貌似红外不能做全双工,你有么有什么经验?

Hi Qichen,
We are trying to design a arduino competable swarm robot pcb, would like to find out the serial - usb chip you told me last time.

关于ACM,根据linux内核文档: The drivers/usb/class/cdc-acm.c drivers works with USB modems and USB ISDN terminal adapters that conform to the Universal Serial Bus Communication Device Class Abstract Control Model (USB CDC ACM) specification.
新版的Arduino Uno 在linux 下面就会成为 /dev/ttyACM0 而不再是/dev/ttyUSB0
