I think the Patronus makes a very interesting option
as a means of communication between Order members. But
a Patronus is very powerful and advanced magic, and
not a whole lot of people know how to produce one.
Even Lupin, a DADA teacher and Order Member can't
produce one (remember during the train ride to Hogwarts
during PoA?), Sirius seems to be able to do it (in OoP
he tells Harry that he would have enjoyed a fight with
dementores over his soul), and I can't even imagine
Hagrid producing a Patronus. It has to be something
much simpler and at the same time more complex,
something that travels really fast and is accurate,
what it may be I have no idea.
