I don't recall anyhone highlighting an actual multipedal PSU that could handle the Pod HD.  The problem is that although the voltage requirements are modest (9V DC), the current requirements are way higher than most guitar gear.  The sticker on the the bottom of my HD500 claims a minimum 2.5A draw is required and the standard PSU supplied with the Pod (DC-3g) supplies more than that.

Two options that may be of interest.

1)  if front of stage clutter is an issue then you might consider something like a pedalsnake.  This allows you to route signal and power through a single snake to front of stage and therefore keeps all the PSUs out of the line of fire.  The rub is that, on paper, the pedalsnake cannot handle the power required by the Pod HD.  With that said, we had some positive messages from the vendor posted on this forum along with positive testimonies from users.  Details in this thread -->  http://line6.com/support/message/342689#342689 .  Make of it what you will.

2)  Someone suggested a multipedal PSU that came with a built in AC slave socket that allows you to plug a secondary PSU into it.  This means that you have the main PSU providing power to any pedals and units that can run on standard 9V/18V with modest current requirements and then plug the Line 6 PSU into the slave socket to power the Pod.  This ain't perfect but at least means that you just need the one mains power connection at stage front.

Can't recall the name of the product but will post if I find it again.  More 'warranty-friendly' too
