As I mentioned on another thread, his tactics are nothing new. We got baggies of ice from our team staff every 5K at the 50K World Champs in Doha last yr and the 2011 PanAm Games marathon in Guadalajara. We were sticking the ice baggies in hats, over our heads, in sports bras, and even more effectively down our shorts (!). I grabbed a new small water bottle every 5K and stuck it in my shorts so I had fluids the entire race. Even at the 100K WC, at the aid stations each country got their own tent and tables, and athlete could put whatever they needed there. Athletes were changing shoes and gear, while grabbing bottles/gels/etc and continuing to run. I want to say they even gave us an extra race number if we wanted to change shirts. You can do 'drop bags' at many of the road ultras as well.
As long as you're getting what you need at an aid station (whether handed to you or grabbed off a table), anything is fair game. Any aid from outside the aid stations is prohibited. The person handing the aid essentially has to be stationary.
If his calves were cramping, I'd be surprised if AlSal doesn't know about HOTSHOT.
What I really question is athletes possibly giving themselves an IV of saline pre-race. I saw a syringe floating in the porta-john before the '11 PanAm Games marathon. That was definitely the most shocking and eye-opening thing I've ever seen.
