You mean "software fault tolerance". There is a project under Linux, I believe. I don't expect it to bear fruit any time soon. The first release of the stuff at Novell took more than 6 years to get working. Anecdote: During one of the early demos of SFT at Novell, the demo was to drop an anvil on one machine and have the failover operate transparently. One time, the anvil dropped, and, since they were using thinwire at the time, the anvil crushed the ethernet card and shorted the thinwire. After that, the demo used two cards. 8-).
