After Running OpenNTP for a while now, I feel less uncomfortable with it - after the first 12 hours or so, the clock swings (+/-12ms) evened out, and it's staying quite comfortably within +/- 2-3ms with very little jitter. In the following output of 'ntpq -c peers', the system in question is 'balrog-priv'; note the odd reference clock - I think that's an artifact of the minimal implementation that doesn't allow that level of querying. In fact, for the most part it seems to stay well within 1ms (it refers to no-such-system, dies-irae, and the local system I'm querying from).
