Regarding (2) above, if Piwik import_logs.py deals properly with logs from multiple servers, I am running a script on a folder full of logs, and see this output:
This is while processing a log from these dates from Server 2 or 3 when it already processed the file for the same date range from server 1.
Is this a misleading message (it seems like it purged the data for server 1's import) or are there additional steps needed to ensure the logs from server 2 through N are added to the data imported from server 1?

To re-process these reports with your new update data, execute the piwik/misc/cron/archive.php script, or see: [piwik.org] for more info.
