I don't really understand what you do. Describe more precise... There seems to be something like a Java API for the iButton devices, with Linux support announced. Try to get your apps run with that, with the iButton reader device hanging at the server serial port (should be easy, as well documented). Then get the reader device moved to the workstation by having the WS running a modemserver (or so) and map /dev/ttyX1 to the network exported modem device - if you got that far, ask again. Another solution attempt: If you have (as I understood) a Windows computer (your "server") having the iButton, and windows-client machines only (as active* is MSIE only, AFAIK!?), you can mount a linux-exported serial port under windows too! That could cost you some dozen bucks (I would have to look it up, don't even remember the program's name for now), but it could work. But I don't see the point: Why attach an iButton reader to a LTSP client when it cannot run the software to access iButton? Or do you use vmware|Win4Lin|wine|...? I wonder if the iButton manufacturers would like to support ltsp-iButton project... Imagine an iButton based internet cafe (LTSP workstations)- start costs would be (as I understood their website) about 20 Euro for reader device per workstation, plus 3 Euro per customer. Fair deal, isn't it?
