Give me a break...  There's nothing to stop you from doing that as
a stackable fs, cachefs-based filesystem, fuse-based filesystem,
CODA with trimmed-down server that does scan-on-commit, et sodding cetera.

Again, do you or do you not expect the malware to be active on scanning
host?  Yes or no, please.

These two variants are so fundamentally different that discussion without
clearly indicating which variant you are currently talking about is absolutely
pointless.
