alternatives to using itpc:// for one-click subscriptions

[panimat]

Hello All - Hopefully you can help

I know that if you use pcast:// or itpc:// as protocol in a link, users will iTunes installed can access 1-click subscriptions to podcasts in iTunes.

Is there a way to do this without out using the pcast or itpc protocol?

I support a system where the supported protocol values cannot be edited

Thanks!
