Interesting write-up on the notion of a SaaS client or a "serviced client" via Phil Wainewright at ZD Net.  The line between pure on-demand and what takes place locally is blurry especially if you look at the capabilities of Adobe’s AIR announced this week or Microsoft’s Silverlight.  Makes me think of my post last year on the cycles of computing – centralize, decentralize, centralize, decentralize.  So what say ye Jim – ready to admit I may have a point here?

Update:  More on this and Salesforce.com’s take on AIR here.
