Perhaps. It would mean, that for every site there should be two instances and 
two DNS entries etc.
My worries for the next 2/3 years is not only volume per site, but also more 
sites. Some sites consists of 20 files max and are totally dynamic, so a 
restore from backup or even weekly tarball is easily setup on a second 
machine if one machine fails. If traffic does shoot up fast, then there is 
new budget :).
The larger sites have more media, like screenshots. We're talking > 2GB of 
images and growing for our games site and there are plans for more 
multimedia/image-heavy sites. Even with rsync, this takes time to sync and a 
much more suitable solution is a stripped down apache geared towards serving 
images (keep-alive, mod_headers, mod_expire) and prolly an inbound squid.
For our main site, I'm already considering load-balancing in a simple 
round-robin, because it has doubled traffic over the last year and is still 
growing, but I'd rather have one copy of a site to worry about.

Or maybe I should think about a NAS solution...
