Excellent graphics. I work radar TMA airspace where, if aircraft are anywhere near each other at the same FL (in your example both aircraft are within the area of conflict, I assume they are at different levels) they will be locked on headings and know about each other.
Procedural sep's are designed with a fudge factor, perhaps someone with a penchant for ICAO Doc's and the like could advise if 1nm off track within an airway, (assuming that nav is without reference to VOR or other ground based nav aids), is within tolerance or not??
I still maintain that on bi-directional routes (even if in radar coverage) it would be prudent to offset, if only 1/2nm, especially in RVSM airspace.

I would be happy to fly with you on the condition you get me to destination 'unbuggered' and if that includes offsetting then go for it!!
