"The actual media platform technology behind EOS is being developed with people and technology Cisco acquired in 2007. Cisco acquired privately held social-networking play Five Across in February 2007. Later that year, Cisco bought the technology assets of privately held Utah Street Networks, the operator of the social networking site Tribe.net.
""Those companies and certainly their people formed the basis of what we're doing, particularly the Tribe assets, which have proven to be very valuable to us," Scheinman said.
"The EOS platform itself is a Linux-based LAMP stack (Linux, Apache, MySQL, PHP) with a Java middleware component.
"While Cisco maintains extensive datacenter facilities -- where it hosts its WebEx Web conferencing service -- EOS is currently hosted by Cisco partner Savvis."
