well it certainly seems judging by the end of PFK that at least one sequel is intended, so I imagine so.
some of my favorite podcast fiction, which can be found on podiobooks.com, includes everything by Nathan Lowell (the golden clipper series starts with 'quarter share,' a good place to start), The Prophet of Panamindorah series by Abigail Hilton, and How to Disappear Completely by Myke Bartlett (this is not to everyone's tastes, and its quite lengthy, but I thought it was just fabulous). Also consider checking out decoder ring theatre, old style radio drama, quite fun.
