Two issues we've seen with IP based load balancing are:
Super proxy farms (like AOL's) will bounce users around to different IP
addressed proxy servers so to decrease bounces in your server farm you'll
need to expand the IP sticky range from a single IP to something like a
class C address block.
Increasing the sticky scope to a class C block will likely result in one
server in your farm receiving more than it's share of load.

fun discussion. I think most hardware load balancers use the IP address,
which is also one of the compliants many people have about them. Atleast if
you ask Resonate, which makes software load balancing. I believe Cisco
routers can also use session based load balancing, which gets around the
performance issues of lots of traffic coming from a specific IP address.
