That's very true, and GovTrack actually uses the House's roll call votes in XML to get that information. The RDF URIs for people are also derived from the IDs used by Bioguide and in those roll call votes. The progress that you mentioned is good, but not having the same information and structure from the Senate makes it much less useful than it would otherwise be. If I have to screen-scrape *some* of the votes, or some of the text of legislation, I might as well be screen-scraping all of them, really. But, yeah, some XML is better than none.
