This means: Very high cost (7$/minute), low datarate (64
kbit), not reliable and long delay (up to 4 seconds from a
datapackage is sent until an ACK is returned.

once a day.

file (via e-mail) and then do the merge at the subscriber

Yes, data will change both sides. But the application will only allow Inserts both sides, Deletes and Modifies one side. (Hopefully)
