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 <i>too</i> much and uptime and reliability would only be as good as the weakest link, which may well be the telco's anyway.
