I have read many times on this and other forums of reputable vendors of pods and rock selling same with VISIBLE evidence of one of flatworms, anenome or aptasia. We have the right NOT to expect that contamination. The solution is that complaints of that nature should be investigated by the above organizations and if substantiated sale prohibited. In that way these vendors will take steps to clean up their act before the reef cops step in.

Let's see...you want wild rock, but you want none of what you deem "nuisance life" that come with wild rock that's common on all reefs? Solution: don't get wild rock!
I've got some Aragocrete in my garage I can sell you for $3/lb...
Let's say you want your rock cleaned of nuisance Aiptasia and pods. The solution there is that the LFS needs to have a holding tank with either Berghia sp nudi's and/or a Copperband Butterfly to chew off the Aiptasia. Isopods? Well, good luck there.
Off the top of my head, I don't know of any species specific predators for that particular pod. I guess you could throw a Pseudochromis sp in there or something to get rid of them, but also expect all your other pod and bristleworm life to be eaten as well. Also, what about Pyramellid (sp?) snails that irritate clams? I think you're asking a lot here for the LFS to clean off all their rock 100% of all the "bad" life. If the LFS goes this route, expect your cost of live rock to increase.
IMHO, if you want good live rock, you should expect that you're also going to get some nuisance stuff with all the good stuff you get from your rock. This is part of the price of having a cool looking reef.
I will also say this in regards to setting up a reeftank: there's more than one way to skin a cat. I've seen some very nice reef tanks setup with wet/dry's, fluval canister filters, etc. Each setup has it's own set of problems and takes a different mentality to run, but it can be done with no adverse effects to the inhabitants. If you have a wet/dry, add some macroalgae to a refugium on the system to suck up the nitrates. Heck, what do you think the Eco-System Miracle Mud setup is anyhow?
What you need to focus on are the parameters that your livestock need to thrive: salinity, temperature, light, oxygen saturation, calcium, alkalinity, etc. As long as those things are provided for properly it doesn't matter how your tank is setup. You can do this with UGF's, W/D's, skimmerless, ATS, Berlin, DSB/Berlin, etc. It just takes a different set of procedures to get the end result is all. I seem to remember Borneman echoing this same thought on Reefkeepers a couple years ago... Personally, I ascribe to the DSB/skimmer method myself but I'm certainly open to other methodologies.
I hope you don't feel that I'm flaming you as I'm not, I just find it interesting...
