It would be possible that, instead of Hopebot uploading the stats, you could have another program upload it.
On my server, Mr_Omally is hosted on the same computer that hosts the stats, so, there is no upload, it just writes direct access.
You could upload PISG stats to the server, and just have an automatic FTP program upload the raw logs to the PISG directory, and schedule a CRON job on the server itself to process PISG stats....
