They updated the file to v10. It looks like it tracks pretty closely with the imaging data now.
I downloaded the v10 files and indeed it tracked well, differing from the position given by
http://lroc.sese.asu.edu/whereislro/ by only a few minutes. BTW, the "Where is LRO" site now seems to be gone (check link). So the question becomes "Where is Where is LRO?"
I hear that up-to-date SPICE kernels are provided to the various centers on a daily basis but those aren't available to the public. That contrasts to, say, MRO, where updated files are continually posted to the NAIF public website, including both planned and as-flown instrument pointing files (so-called CK kernels). Cassini also does this. My understanding is that the older programs (particularly Cassini, being an old-school big budget project) were more committed to this. In Cassini's case, they even provide "science plan" kernels containing text information about the type and purpose of observations, correlated with instrument command sequences.
Eventually the pointing and trajectory files will be posted to the PDS, but only after 8 months or something like that. So near real time for LRO looks to be a no go, as far as the public is concerned.
