AlienForce is an open source platform for building high scale networked applications (not solely web sites, also TCP services, etc.) It is based upon a closed source commercial system called BenTen that was developed in 2004 by Arts Alliance Labs and powered several large sites such as large portions of JohnKerry.com, Povo and many others. The web has clearly evolved since then, and AlienForce is an attempt to keep the best portions of that effort while adopting existing technology wherever possible.
