Just a quick update to say that after deploying to enough devices, the gpodder.net feed service is having some issues keeping up with the load. This has lead to listen up users not being able to get new episodes. I have written to the gpodder people and I'm awaiting a reply. I'm considering other alternatives at the moment.
Update The gpodder guys are generously setting up a new server to handle the new traffic. Hopefully, this should be fully resolved shortly.
