Currently I'm hosting it on Cpanel. I contacted Softaculous and asked them to add Castopod to their webstore, then waited several months to a year-ish. My plan is to move the audio into Minio S3-compatible storage and then move podcast (yikes) onto my hardware. :)
I want to say Thank you so very much for telling me about this. This tool is absolutely incredible. Worth every penny. Thank you.
