The 'pulverisation in the pack' is a surmountable issue. When I was in the army I was on a semi-tactical exercise. Periods of 'war on, war off'. We had been fighting in full kit - packs and all. On the 4rd day on a non-tactical morning, I smelt the aroma of bacon and eggs. Some of my guys had been carrying eggs for 4 days, jumping in and out of aircraft and APC's - generally rolling around and crushing their packs. Somehow the eggs survived in a commercial egg-holder plastic frame designed for hiking. With a bit of initiative, it's doable I guess.
If it was me, I would have just ended up with smelly raw omelet in the bottom of my pack.
Oh, and for avocados - don't forget the tabasco!
