Last week we wrote about troubles at VoloMedia — the company hasn’t yet raised the funding it’s been seeking for a while, and got rid of its ad sales unit to focus exclusively on technology development. But at least it’s not treading water; Volo has just announced two product updates, both integrations with Google products. First, compatibility with DoubleClick DART — so DART publishers can use their existing ad management platform for portable media as well. (This is something that Volo competitor Kiptronic, which just got bought by Limelight Networks, already had.) And secondly, publisher access to iTunes data within Google Analytics via a plug-in downloaded by podcast listeners.
