According to the code remote courses are supposed to be displayed on home page and in course list block

The function get_my_remotehosts() always returns empty list. This happens because of the following line in confirm_mnet_session():

$remoteuser = mnet_strip_user($remoteuser, mnet_fields_to_import($remotepeer));

It strips out 'myhosts' attribute in $remoteuser.

If we decide that we don't want to list remote hosts, we need to clean the code to remove all functions querying and displaying it.
