I guess it would require people that have good contacts (initially) in order to have host that are known and trusted as well as have contacts and knowledge to help organise. I guess future hosts could be found from people who entered the previous proxy or at least one ‘well known’ proxy that year. 
I guess I saw it in my head as similar to a national racing series (eg BTCC) where cars race at one track, or even 2/3 if there are a group of like-minded people in the local area. Cars would then be returned to owners so that they could be set up for the next round (if rules allowed). The thinking behind ‘home’ tracks is that each on each is different. One could be high speed long straights, the next could be super small and twisty. 
Like you said though, organisation and I guess trusting people is one of the main things.
Didn’t think a thought while doing the dishes would go this far! 
Thanks for your input guys!
