Yes, important point there. The choice to host across multiple subdomains should be made for a reason, not by default. If the subdomain is an essential part of the user's request (Google up "Basecamp style subdomains" if you're not sure what I mean by this) then it's possible that you'd want separate cookies for each subdomain. In the vast majority of cases however, the application isn't inferring anything from the subdomain, and you're potentially losing PageRank.
Making the configuration at the web server will help you with both problems, if it is in fact a problem to have more than one subdomain, whereas the Rails-only solution helps only with cookie management.
