This is awesome, back when the Tell-Me API and Voice XML was going (over a decade ago?) I had my cheapo pager pushing me scraped news alerts and all kinds of things. I think the one big hurdle would be for large organizations that worry that sensitive data would have to flow, or worse, that they'd come to rely upon the thing too much and uptime and reliability would only be as good as the weakest link, which may well be the telco's anyway.
