Agreed.  They are heavily rate limited to deter spam so they're not great
for mailing lists.

If you actually want to send SMS, you need to pay for it through one
of the many SMS API services.  It costs on the order of 0.7c/message
to US numbers which seems pretty cheap to me, but I suppose that
depends how valuable you think your lists are.

Trying to integrate directly with mailman would be a nightmare, but
you could easily set up a kludge where people subscribed separately to
the SMS forwarder, subscribe a special local forwarder address to the
mailman list, and then tie a script to that address that takes the
contents of the messages and passes it to the SMS API.  (Stripping out
all the extra cruft, of course.)
