I tried to indicate that I didn't literally mean the current eTraveller, but could have been clearer. I meant that we need to get at the information that (for e.g. TS8) is in the data store and indexed in eTraveller with very low latency.
We should be treating photo-lsstCam data taken with the CCOB as if it were lsstCam or auxTel data taken on the mountain, and there we will need immediate access to the data. So we're going to have to face this problem at some point, and I think we should face it now.
I would be unhappy with a solution that works for CCOB with a 60s delay before DM can see the data. This would strongly discourage the camera from ever learning to use the LSST Stack.
