"forwarding to the active HSRP device" and "only the active HSRP interface
answers ARP request" doesn't particularily sound "active-active" to me :-)
*This* is what happens on any 6500 that does HSRP on a SVI...
GLBP is active-active in that both L3 routers will accept packets to the
world, instead of L2-forwarding them to the other one inside the SVI.
