orcallator.se only reads from a single log file, so you won't be
able to monitor the different virtual hosts if they each write to
their own log file.

Nope, that should be it.

If you want it to find the new source input files as soon as it can
get around them, then either bounce Orca or better yet send it a
SIGHUP.  This tells it to find all the input files on its next pass.

Not if you use SIGHUP.  Also, the find_times configuration parameter
tells Orca when to search for new files.
