From Peer 2 World:
Weezo turns your computer into a powerful and secure web server, thus enabling you both to access your PC for personal use (remote PC turning on and off, remote desktop, file exchanges, and webcam monitoring), and share your content (photos, music, videos, files, and Web TV) with whoever you want. A simple web browser is required to access your PC, with an OS-like skinnable interface. Shared resources are connected to password-restricted user groups: you choose who can access what. Security can be enhanced by using an SSL-encrypted connection. All of this can be done instantly as there is no need to previously upload required files on a distant web server, and without any size or format limitation. Privacy is also entirely preserved as no personal data goes through our servers. Weezo setup, configuration and use have been designed with simplicity as main concern. Weezo is mostly open source, and relies on open and secure technologies such as Apache, PHP and OpenSSL. This permits add-ons to be easily developed, limitlessly extending your site: host your blog, open a forum, and check your email.
What's new in this version:
Version 4.2.3 fixes issue with integrated resource creation.
Really simple, lots of functionalities, extensible, great "Web 2.0" interface, looks really nice :), no centralized server, registration optional, open technos (apache / PHP). Definitely worth a try for those who have a need for this kind of software...
