We have done a sort of blog post/tutorial on local molecular clocks to look at an interesting latency phenomenon in Ebola virus in non-human hosts. This is work in progress based on genomes published recently by DRC/INRB from current and recent outbreaks. http://beast.community/ebov_local_clocks.html …
If yes, then we know that latency is a function of the (reservoir?) host, and not actually something intrinsic to a particular (DRC) Ebola virus lineage. Completely what we would expect, but nice to explicitly test (especially given, ehm, certain papers...).

I think it may be a mechanism that the virus has used to persist in the reservoir - sweeps through a population (roost?) and if it isn’t able to move on to another, then much later it can re-emerge from an older bat to infect all of the new naive bats that have been accumulating.

Yup, I think that's totally reasonable. I *do* wonder about the potential for an intermediary (amplifying? 'adapting'?) host too though - e.g., great apes. Could the virus create latency in bats more generally, but then bounce between species (prior to outbreaks?).
