The audio for Podcasts are just .mp3 files - they can be hosted on any webserver.
The Podcast data is held in an rss file (a special xml format) - so you just need to add this line
AddType application/xml .rss
to your server's .htaccess file. Then load the rss files onto your server.
Then just write the pages that display info about the podcasts and point to the .rss files. You will also need a Flash MP3 player - there are a lot of these available - I use the XSPF player. You just load the player .swf file onto your server and embed a reference to it in the pages you create. The player will probably require a playlist file (pointing to the location of the .mp3 file)
Have you sorted your problem? Any information on implementation part.
It was one of those problems that sorted itself. The client backed out of the idea when they realized the costs of the project they had in mind.
There are a lot of businesses out there that you can contract this out to, and the prices are not that high for a limited audience. That would have been the route I would have taken.
It is the on-site stuff that runs up the costs. Camera people and AV engineers, plus lease of equipment (all in duplicate or triplicate for redundancy) start to add up quickly. Using amatuers to run the AV equipment makes for an amatuer production. Using pros makes for an expensive production.
