Then if you wish to use MyphpAdmin remotely, the folks running your MySql domain must set it up, unless you have access to their services with a remote server connection.
It strikes me that the best place for these questions would be with the folks that are running your db... they are the only ones that can allow you in with anything.
PS: What is developed locally? The php code? How do you upload a database to the other domain right now? Can you download the database you want to export. If so, you can use ODBC and bring the MySql tables into an Access DB as linked tables. Then you can export them however you want.
