WCBN - Online Audio Servers?

Jeremy over at Maize and Blog posted this today: WCBN Sports has been using YouCastr as its main audio server this year in order to give listeners an interactive, high-quality broadcasting experience. Unfortunately, YouCastr is changing its service in 2010 and eliminating its free-to-view audio broadcasts; needless to say, WCBN is unwilling to force its listeners to pay for Michigan sports audio. So, today, we are asking for advice. Do you know of any online audio servers through which we can bring you Michigan sports without charging fees? Please let us know if you have any thoughts. Thank you, WCBN Sports
