I guess 1 second could work. It's kind of a bummer though as one of the other apps I was working on is data acquisition board for race engines, where < 1 second granularity is critical. OTOH, that uses 1wire with a microcontroller, so perhaps the dynamics are different.

I find it strange that 1 wire is not reliable as it is used for all kinds of automation and stuff like public transport payment where presence (or not) would seem to be critical... BTW, I've been looking into Inotify (http://en.wikipedia.org/wiki/Inotify), but after trying a bunch of code, I discovered that Fuse probably does not support it :-( So back to square one (File::Monitor or something + callbacks....). If you have any great ideas on this, please pass them on. Thx.
