Podcast Hosting Recommendations, Challenges & Solutions

I just read about a new service called Evova on TechCrunch tonight.  I'm excited about the opportunities that companies like this could offer nonprofits interested in getting their (audio) message on the web.  They are much like Odeo, but they have some cool bells and whistles that I don't think Odeo has adopted yet.  To quote from their site, here are a few of the ways that you could use their service:

nce you get the hang of Evoca, you'll see that it can enhance the way you communicate with your voice. Here's a few ideas:

• Broadcast voice messages to your friends or colleagues
• Produce and listen to podcasts
• Dictate, transcribe and translate [ more ]
• Start a personal diary. For real this time
• Record, store, and share oral histories
• Voice your political opinion
• Journalists, capture and store your stories more effectively
• Singers, want to spread your song?
• Storytellers, record your narrative and excite the world's imagination
• Communicate with voice
• Add your voice to your blog
• Record your notes-to-self on the fly and access them anytime, anywhere
• Find audio. Search a word or phrase - we'll bring you right to where it's said
• Listen to what your world has to say!
• Subscribe to other member's recordings using RSS

There is a free level and a $5/month pro service.  I'm planning on playing with it some and I'll post more if I have anything to discuss.
