The "virtual" device is an interesting idea. Some issues with security (we don't currently let the 1-wire system effect other hardware or run other programs). I'd envision this as a special "owjob" that looks like owserver, but responds only to a directory with properties linked to arbitrary programs. The programs and property names could be user-configurable. Perhaps a better name than owjob can be suggested. So you run owjob -p 3333 "LED wo integer /proc/diag/led/ses_switch" owserver -s 3333 -u And in addition to the full content of the USB bus, there is a directory "job" with entry LED that is write-only integer. > Next question: running 2.8p4 on a nslu2 running debian, and 2.7p21 on a > wrt54g running OpenWrt backfire. Both devices need to share 1wire devices. > Do I care? Probably should be fine. The program might be confused in the few cases where the slave property definitions have changed. The owserver protocol is completely backwards compatible.
