> Do you think it would make sense it's be an option to offer the cache as an optional download with Houdini?
We'd really like to get to this point, but at the moment NVidia own the cache and its a black box to us. And its heavily specialized to CPU, machine makeup, etc... (ie not just GPU + driver). So there is nothing we can do today, but we are working with NVidia to address this in future releases, so watch this space.
Good to know people are making use of the pre-compile feature in anycase
