I am pondering a facility where any subscribed person can send a message
to an address and all subscribed people then see this.

Very much like the old style mailing lists but brought up to date for smart
(ish) phones.

Twitter seemed an obvious candidate for distributing a single message to
all subscribers (watchers) but accepting and filtering an incoming Tweet
and automatically Retweeting seems more of an issue.

A mailing list might be an option (proven technology) but I am not sure
that the proposed user base has anything more sophisticated than SMS in
common.

Any suggestions most welcome.

You can set up a yahoo group that remains private and you as admin/owner
invite members to join. They then opt for emails relayed out as you
suggest or a daily digest, admin email only or no email at all.
Emails go out to a given email address and up to them if they can see
that on their phones.
I run one of these for my old school year class mates and it works well.
Includes file areas where members can store documents/photo albums for
all members to see.
