While not a podcaster another person I would like to see (hear?) as a reader for escape pod/pseudopod is Lenny Henry (was the reader for the audiobook version of Anansi Boys by Neil Gaiman).
Speaking of Gaiman, just noticed he has a new book coming out June 26th M is for Magic, cover looks like it's more one of his "children's" books, anyone know anything about it, as this is first I have heard of this one, and wasn't much available info wise on Amazon.
