We use the load balancers for traditional load balancing, full proxy for http/ssl traffic, ssl termination and certificate management, ssl and http header manipulation, nat, high availability of the physical hardware and stateful failover of the tcp sessions.  These units will be placed at the customer prem supporting our applications and services and we'll need to support them accordingly.

I've used LVS and other Open Source solutions in the past.  As others
have alluded to, these require knowledge and experience with the
underlying OS and network stack that's often lacking in many
organizations.  A good hybrid solution which implements all (I think) of
your requirements is Zeus (http://www.zeus.com/)  It's a software
solution which you can deploy on your own hardware.  It's been very
solid in my experience.  You can deploy the software in a clustered
configuration if needed, though I've only used it in an HA pair.
