Fold.com recently launched a beta version of its personal portal: http://beta.fold.com/. (This domain name alone is quite valuable!)
This personal portal is developed with the latest ROR platform +MYSQL, I believe that the development difficulty is much smaller than the previous personal portal, if you are interested in its development can see the developer's blog(to use proxy access).
Fold support FLASH, HTML window, provide weather, note, RSS customization, clock, calendar, Flickr support, you can shrink, restore, drag, but the only pity is that only support Firefox browser, IE browser can not use normal functions.
