Yea, i discovered you need a pretty up to date computer to run eqoa at full speed. I seriously upgraded my PC, and now eqoa's load time is practically nothing. Coaching from place to place, loading times take no more than a 6 or so seconds. (I can coach faster to FP from BW than my wizard friend could evac there.)
Also a noteable difference, is that when I go into first person, look up or down to keep several in-game objects out of my characters vision, I can move at incredibly fast speeds, so fast that I am able to outrun mobs with super sow... Which makes great use for getting coaches.
I've had little luck at getting information from people on how to start making one, aside from needing a router that can re-direct traffic and packet sniff or something.

^ was probably the only sort of useful information I could find.
I really want to try and figure out how to do this, we all know EQOA wont be around forever, so we need something to have for when that fateful day finally arrives. :(
