Will data be changing at both Publisher and subscriber?

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
totally offline?

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