The other day I noticed that it was smoky while idling... Rev the engine, big puff of smoke. Pull over to the roadside and its not doing it. I then thought that maybe it was just a piece of plastic that I picked up and got on somehing hot... But then a day later and its doing it again intermittently. It doesn't appear to be related to how hard I push the car. No degradation in power, boosts like normal. But that last respnse really has my heart sinking...

What would be your next steps? I could shell out for a leakdown but is like to know of there's anything a bot more simple that I could do to diagnose.

Sigh..
That sucks. Unfortunately Subaru engines are very sensitive. If you have the stock parts, go back to stock and get a leakdown ASAP. In the meantime, remove the oil filler cap while the car is idling and see if there is any smoke coming out. If you see any significant amount of smoke your fears can be confirmed. :'(

Also, turbo seals are a possibility based on the symptoms you describe. If you remove the downpipe after the car sits for a while, you may be able to see some oil in the hotside. This is hit or miss though as it burns off very quickly. I would still recommend what i said above, but if the leakdown + compression comes back clean, take a closer look at the turbo. Also if you have a change, pop the intercooler off and see how much oil is in the Y pipe and the throttle body coupling. A little is normal, but if you see pooling or you're able to drain oil out of it, that definitely indicates a problem.
