Sweetcron is a new open source software that helped one to create a self-hosted lifestream service. Currently developed in Japan and in Alpha phase, it probably will be released soon by its creator, i.e. a php programmer called Yongfook.

At this moment, very little information about this newly open source software, but the front page of Sweetcron stated that it will be an open source RSS aggregator, with a bunch of php source files that one can easily debug and improve from it, and of course, a default CSS theme readily offered to the users. Since it is an open source software which you can self-host it with your own domain, it also means that you need to configure the update yourself.
