Jack Vinson picks up on some enterprise syndication features in KnowNow's new products. Looks like a meld of web crawling, feed crawling, and event notification on a big scale. There's also a hint of enhanced aggregation, which pulled Attensa's CEO, Craig Barnes, into the conversation. Apparently, Attensa is also doing enterprisey things with RSS.
I'd have to drill down on the postings and press releases to see if there's any there there, but where I feel desktop aggregation is a bit moribund, large corporate customers may be driving some "hidden" innovation.
