One solution is to use a content switch - which not only allows you to group
servers that are effectively serving the same pages (almost like
clustering), but also is pro-active, in that it can cache pages, and will
update the cache as soon as content changes are detected.

Cisco Arrowpoint switches come to mind - but I'm sure there are many more.
Obviously there is a financial outlay for this type of solution, so it
depends on the overall redundancy requirement and it's importance as a
visible platform!
