Well, Mochiweb is a general purpose web server, it doesn't do anything 
rabbit-y by itself.

The closest thing to what you're looking for is currently in the 
management plugin - see /api/exchanges/[vhost]/[name]/publish and 
/api/queues/[vhost]/[name]/get, documented at:

http://hg.rabbitmq.com/rabbitmq-management/raw-file/rabbitmq_v2_6_1/priv/www/api/index.html

If you want to publish from a shell script, the rabbitmqadmin tool that 
ships with mgmt should be more convenient than curl for talking to this API.

http://www.rabbitmq.com/management-cli.html

But bear in mind that this API doesn't make any attempt to deal with 
acking in either direction - if your HTTP connection is interrupted you 
could lose messages. I don't know if this is a big deal for you. If it 
is, I would write some little script with one of the Python or Ruby APIs 
to do the right thing over AMQP.

Cheers, Simon
