SQL Server Table DML

1) We have 2 SQL Server 2005 servers databases with disconnected architecture i.e. wireless.

2) For some tables, we need unidirectional copy of DML changes from one database to another and for others a
bi-directional copy.

3) Replication is not possible. Triggers are not allowed. What about backup and recovery? Any files that get generated
can be copied from server to server using WAP.

4) Can we read from .ldf log file to generate DML statements to be applied on the other side?

5) Can we take Trace to file/table for DML statements/events that occur on a single table?

6) What we are planning is have emp and emp1 in one DB same initially and all differences will be stored in a text column
i.e. inserts, deletes and updates that occured later. From this into a file which is transmitted to the other server.

7) Can you suggest any additional ideas or strengthen what I proposed.

8) Can tools help in this regard?
