server failover is a risk?  Single servers because you have raid5 is all
good and well, but there is reasons for doing server failover, such as
hardware and software upgrades and maitenance.  It's all good and well
haveing rocksolid storage when your network card fails!

I believe I had suggest something very similar 

( ssh user at box1 ' cat httpd.log ' ; ssh user at box2 ' cat httpd.log ) | sort
> newhttpd.log ???
