Reality of Tie Down (Tiedown) Space at SNA

There doesn't seem to be a lot of information available on the web
(first time for everything) with regard to tie down space in SoCal
(specifically SNA). What is the best way to go about this. I know
there is a waiting list as long as my arm (or longer). But I've also
been told that many people are on the list simply get the spot and
sub-lease it. If this is true, where do I find these people?

I also know a T-hangar is impossible... but there must be some way to
get space (for a single) at at SNA... even if it is twice or three
times the normal price. No?

I guess I've come across a major problem that I never thought about
before.
