"Phoenix Technologies' HyperSpace is also built on Linux and
various other FOSS applications plus some proprietary code, but it
is significantly different from Splashtop. It is installed to your
hard drive, and it operates in two modes: hypervisor or standalone.
Hypervisor mode, called "HyperSpace Hybrid", lets you run it
side-by-side with Windows, and switch back and forth without
rebooting. Hybrid mode requires an IntelVT CPU. "Dual Mode" is for
systems without CPU support for virtualization, so to switch
between HyperSpace and Windows you need to reboot.
"Unlike Splashtop, you can purchase HyperSpace separately and
install it on your PC. Hardware support is still limited, so check
the specs first. HyperSpace comes with a Web browser, full
multimedia support, wireless Ethernet and 3G support."
