Yes I would be VERY interested in a Maemo podcast. I'm a podcast junkie. You may want to check out "The Bad Apples" podcast for advice. The host, Klaatu, is just a great individual, and he seems to love helping people with Linux. He has answered every email I have ever sent him. He also records all of his podcasts on an N800.
Also consider doing hacker public radio episodes if you're not sure if you want to commit to a full on podcast. I keep looking for something to do one on, I just don't know S about anything interesting.
Armored penguin is no more? I liked your show. Should I remove it from my feed list.
