I would do at least 5 Podcast edited down at first so the hosts could get everything down right. Proper volume, equalization, etc. Make the show tight, no dead air at all. Make a special invite to 20 guys to call in for the 5 edited down podcast for testing. Once we go live then the routine is set. The sound bytes are ready...etc. I am not sure what hosting would be price wise but ideally you would want your own server so bandwidth limitations and storage limits would not apply. I have about 40 gig in music alone and there is no way you could upload that to an external host. It would cost a fortune.
