Create a mail message to the remote users with
1) a copy of the database as an attachment
2) a database doclink
Also in this mail message, add some instructions on how to detach the attachment and where to place it (in the Notes data directory). After the attachment has been detached, the instructions should ask the user to click on the doclink. This will search for the database replica locally and open it; it will also place the database on the replication workspace page.
If the attachment is large, you should warn remote users that you are sending it to them so they don't think that the replication is hung.
