disclaimer: I'm the LVS-HOWTO maintainer and have been with 
the LVS project since 1999. LVS is designed to handle 
failover and high throughput of services like http.

UtraMonkey is an HA wrapper around LVS. It comes with all 
the files for LVS and is a popular way to set up an LVS. 
There are other ways of handling failover for LVS: eg mon 
and vrrp. The UltraMonkey author is busy and is hard to get 
ahold of. However the LVS mailing list is full of people 
who've set it up if you need help.

Usually we hear of other technologies of interest to LVS 
users on the mailing list. Noone has ever talked about 
OpenSSI or OpenQRM on the LVS mailing list.
