Analysts at Piper Jaffray expect Audible to benefit from Apple's move to include podcasting facilities on the iPod and in iTunes.

"We expect increased awareness in downloadable spoken-word content could translate into an increased number of iPod users willing to pay for Audible's content," the analysts said.

In the long term Piper Jaffray believes Audible could become a provider of delivery and infrastructure solutions for content providers that publish paid-for podcasts, reports Forbes.
