we may have to implement something similar in the future, and I'd be grateful if you could send me an update on the reliability of this approach. In theory it should get you best response time, but I worry (partially from timer event expirience<bg>) that the event may hiccup or not fire always - as long as enough intervals (or different timers) are in play I see timer usage as the approach "with safety net" - but less elegant.
