This paper presents the results of a semester's experiments with producing instruction in "castable" format for iPODs and PDAs. The program involved is a non-traditional graduate computer science program emphasizing "applied computer science" that also includes integrated distance-learning technology. Existing lecture recording and web-streaming technologies were upgraded to also produce "castable" versions of the lectures for downloading and viewing on mobile devices. Observed student use and survey responses were used to evaluate the pedagogical value of these lecture formats.
