Utah's Division of Purchasing has an RSS feed of current solicitations. This is an RSS version of the current bids page. Of course, the good news is that if you're interested in following Utah RFPs and know how to use an aggregator, they'll just show up on your desktop without having to remember to go and check the page. I wish they had a "what's this?" link next to the RSS link to tell people about how to use RSS. If more states had RSS feeds of their solicitations, you could do some nice work with a filtering aggregator to deliver customized solicitation notices for multiple jurisdictions. Since solicitations frequently have addendums and updates, there's a need for extensions that consistently render the solicitation number or some other correlating information so that addendums can be linked to the original solicitations.
