I worked with Blubrry to create a new donate tag:

If the feed supports this tag, a simple donate link appears in SkipCast and when tapped, takes you directly to the donate page. This tag can be supported by any Podcast client.
To me this is a clear win-win situation, though the feature depends heavily on adoption of simple, easy to use and deploy donation services, and of course the user supplying the tag.
One good example of the donate model working is the Crate and Crowbar podcast (PC Gaming). They created a Patreon and literally shut it down after a few months. The reason: they got hundreds in weekly, recurring donations and simply didn't need that much money.
Donations can work, and could be a huge boon to smaller, independent Podcasters. This could in turn ensure a healthy ecosystem that's more resilient to monolithic entities.
