Vance,
I've been restricting my postings to things that are "audiobook and spoken word related". The above items didn't quite fit into the podcast audiobooks sticky, and aren't quite regular subscription items.
There is a whole list of Publishers' podcasts that I've been meaning to add as a post (since about October!), but haven't had time --- NAXOS, Simon & Schuster, Penguin, etc. plus book review specific podcasts. I'll try to start that under a separate thread.
Incidentally, on the
Archaeology Channel, you know that the web page has small streaming real-time movies, don't you? They started podcasts quite a long time before offering it through the iTunes Music Store subscription.
This is also probably slightly off-topic (since the audiobooks are "free" but in streaming format), but KCRW, which jumped into podcasting relatively early (making the bulk of their programs available starting March 2005), also has a few great audiobook efforts that could go into the recommended list.
Ten by Maugham, a collection of short story readings on 10 CDs produced by
Martin Jarvis and his wife, Rosalind Ayres, won the
2001 Audie award in the category of Short Stories/Essays/Collections. (A good year for Maugham, the award for Classic Fiction went to
Charlton Griffin's reading of Maugham short stories (vol.1, also available through Audible). That CD set has been used by KCRW as a member promo, and is not available in streaming format on the site, but some of their other efforts, such as
Jewish Stories from the Old World to the New and
Jewish Stories from Eastern Europe and Beyond are there. These are great narrations (Peter Riegert, Elliot Gould, Eli Wallach, Claire Bloom, Theodore Bikel, Charlton Heston, Carl Reiner). For background (Klezmer) music, go to the
NAXOS podcast page or if that doesn't work go to the
NAXOS main site and look under the podcasts menu. Use the
RSS feed to subscribe to the Episodes (about 1 per month) of music from the Milken Archive from the 13-part series on the American Jewish Music tradition hosted by Leonard Nimoy. The NAXOS site also give the current NAXOS audiobook podcast offerings from
this RSS stream. They presently consist of 3 episodes (52 minutes in all) of David Timson reading Sir Arthur Conan Doyle's
The Crooked Man from the NAXOS audiobooks of Sherlock Holmes stories. (iTMS users can search for NAXOS under the podcast directory; it will show the audiobooks, but you won't see all the other categories you can find at the NAXOS site.) NAXOS also comes out with
Audiobook Samplers.
Edited 22 May 2006 (anniversary of Sir Arthur Conan Doyle's birthday) 
Excerpted from the NAXOS podcast pages mentioned above -- sugggest readers subscribe to the original
Naxos AudioBooks Preview and
Naxos Audiobooks podcasts from which these are drawn, and also check the additional material not available in these podcasts on the NAXOS site described above:
Sir Arthur Conan Doyle's A Case of Identity, read by David Timson
Sir Arthur Conan Doyle's The Crooked Man, read by David Timson
Comment: NAXOS Audiobooks Preview podcasts stay listed for 2 months. These direct links to the NAXOS site have been added because earlier episodes are no longer available via the subscription link, so late subscribers would only be able to listen to the end of a story.
Edited 1/4/07: Updated links to KCRW programs (prefixes changed from www.kcrw.com to legacy.kcrw.com) reflecting KCRW's revised web page design (December 2006). Updated NAXOS sampler link to their 2006 sampler. The NAXOS Audiobooks Preview podcasts no longer seem to be regularly updated, although the links given here to older content still work.
