Thanks for sending this around, this is a great overview.
I know vendor dependencies were discussed in a past meeting, but skimming the meeting notes, I can't seem to find the outcome of those discussions. Wondering what the plan is to build against libraries for Houdini, Maya, Nuke, etc in terms of EULAs and exactly how this will be exposed in Nexus?
Regarding CI for OpenVDB specifically, I don't see a problem with sticking to using VFX Reference Platform versions of dependencies. I suggest one of the next steps will be to match the existing build matrix used with Travis CI (https://github.com/AcademySoftwareFoundation/openvdb/blob/master/.travis.yml) and the major component missing in ASWF Jenkins currently is building the Houdini plugins.
