Portability of Applications and Widgets

Talk about portable widgets is not new. After all, 2007 has been proclaimed "Year of the Widget" by Newsweek. Though what I intend to discuss here is more about portability aspects and efforts in this direction rather than about widgets themselves. One of the early entrants in the market was Knofabulator (remember anyone?) which was bought by Yahoo. Then it seemed that they didn't know what to do with it and rebranded it but added no extra functionalities. A few days back it was in the news that Yahoo was releasing version 4.5 of its Konfabulator widget. The new version includes things like HTML and Flash support as well as a better user interface. However, Yahoo widgets are still only for desktops like Vista or XP. However, with Google releasing widgets for Mac a few days back, as well as Mac having widget support and Microsoft supporting widgets in Vista, Yahoo may find itself facing tough competition in a comparatively small market. Such widgets are important if we see them in the light of what is expected of applications in future. Application virtualization is gaining ground and also to be noted is the following vision of Google's CEO, Eric Schmidt.

Netvibes is a company which had initially announced a widget platform to make widgets that can work on Vista, Google, Mac, and even Yahoo widgets. It is called Universal Widget API and has the aim of "build your module once, deploy everywhere". Other companies in this space are Musestorm and Clearspring. Musestorm enables non-programmers to develop rich media widgets and Clearspring specializes in distributing widgets as well as analytics and API. The next step, of course, would be for these applications or widgets to run on mobile as well. For instance, I am sure Google's Android which is to be released next year with Open Handset Alliance will soon be integrated with their Web ToolKit so that applications can run over mobile, computer, and web. And won't that be cool?
