Dear Zeljko, I just can confirm Fuzzyman's opinion. Using irda is quite troublesome and probably impossible for >1 device. Just for one device its even bad, as you have to hold the device in 10cm distance to the transmitter / laptop all the time.
Instead using Wifi is really convinient. The connection is really reliable and is very easy to setup. You just need aditional hardware (WLAN-extension cards) for the Axim X5. In my opinion, there are only two possible scenarios. a) using wifi (quite superior, easy to setup and enough bandwith - but extra cost) b) using usb cables and a usb hub Concerning the cable solution you probably have to switch to linux as a host os, as I don't think that ActiveSync support more than one device at a time. With linux it is feasible.

I don't *know* of any ways to access the Irda port through PythonCE (except perhaps through the new ctypes library). On the other hand you will be able to use TCP/IP over bluetooth/wifi. You should be able to do this through the socket module or using urllib/urllib2 as a wrapper. I would be tempted to run a python proxy server on the PDA (based on HTTPSimpleServer) - making requests to a server running on the PC. That means you would use Pocket IE to display the images. If you don't need to modify your requests too much you could just run a server on the main computer and not use Python on the PDAs at all. Alternatively there is an implementation of PyGame with *some* functionality compiled for PocketPC (I believe - search the archives of this list). TCP/IP is still a good way to push your data around.
