Ironically, at [big e-commerce company], where I work, we're moving away from the dedicated load balancing hardware, though not for any of the reasons you're discussing. Our traffic volume is high and heterogeneous enough to trigger subtle bugs in the LB firmware. Getting debug information is next to impossible when they just start dropping packets on the floor. They're also really expensive, so the vendors' solution -- "You need to buy more of our hardware" -- makes our finance guys cringe.

Rather than replace them with dedicated boxes, though, we'll probably just remove that layer entirely -- clients will negotiate leases onto a single host for a given period of time, with initial discovery through a broadcast mechanism.
