I'd like to have my own custom module alter the message composition in _messaging_sendto_compose(). I don't think this is doable right now but let me know if it is. messaging_sendto should make a hook available that my module could implement. It should make available all the parameters ($method, $destination, $values, $preview) and allow me to alter the $message array.

To give you an idea of what I was doing, I wanted to alter some message params depending on data in an extra field that I added to the form, and also add some attachments: 

 if (isset($values['gateway'])) {
  $message['params']['sms'] = $values['gateway'];
}
if (!empty($values['node']->files)) {
  $message['attachments'] = $values['node']->files;
}
if (!empty($values['node']->field_image)) {
  foreach ($values['node']->field_image as $file) {
    $message['attachments'][] = (object) $file;
  }
}

Question about how to implement this: Should we store the $values (which includes $values['node']) in the $message object, so contrib modules have access to the sendto "context" and can use message_alter() to alter the message? This might be preferable to adding a new hook as I suggested above.

Hey, attachments are in the works in messaging in general, I'll try to look into utilizing that functionality for this module. You could also try hook_message_alter() or similar on the messaging side of things.

When altering the message, I need access to the form values (including the node object, and also any custom form fields I am adding via form_alter). Seems like I need either a new hook, or for messaging_sendto to make the form values available somewhere in the message object.
