I'll tackle the meditative part first. For a long while I thought that desktop web applications were utterly pointless, because a) the GUI is there anyway, and b) embedded HTTP daemons cost so much in overhead (for example, I started playing with embedded Tomcat recently; cool concept but enormous RAM hog and a 10MB installation (which is a lot if you're offering something for download)).
