My 2 cents:

Keep -0.2db headroom minimum, or for the lazy/cautious: a peak limiter set at -0.2db on the master buss should do the trick. (I'm not a good engineer, so I fall into the second category).

-0.2db seems to "hold" it's value better in most software that resamples. Anything higher will almost always end up clipped or limited, in an uncontrolled fashion - as Fons pointed out here, some peaks will invariably be sampled on either side and the software will just pin everything between the samples at 0db. Yuck.

I spent an afternoon last year comparing -0.2/-0.1/0.0db max, and I found this to be the case almost every time. Never had a stray peak at -0.2db
