if you just want to telpath between you and them(not among them), you just need 37500gp (party, spouse, and clan)
much cheaper.
and it need 13th caster level for it and it looks like the spell you want to permanent and permanency have to cast by same person.

DESCRIPTION

This spell makes the duration of certain other spells permanent. You first cast the desired spell and then follow it with the permanency spell.
Like I said, expensive. Though strictly speaking, you don't need to connect every person to everyone else. You could have Bob go with Jane, then Jane with Bill and Bill with Susan etc. Sure you risk the chain breaking if one person goes down, but since speech is a free action you can play planar telephone pretty quickly.
