3.5 and/or PF?
Scrying lets some spells work through it. Was there some greater scrying variant that allowed more spells through? I recall there's plenty of opinions in both if your minion is your familiar, but can't remember any speciffic ones off the top of my head.
In PF, Witch's scar hex can be used to ignore range on some things. In third party PF, DSP's psionic classes with collectives can do this this at higher levels
