Merge Replication across the internet

Hi,
I require to replicate data 2 ways across the internet.
I think merge replication would be the best way to do this.
How secure is it across the internet ?
Is there anyway to create a file out of differences to be applied to
another database.
I am using SQL Server 2000
Srini,
yes this is possible with a few treaks.
To make it completely secure, most people use a VPN.
File-based replication is not possible.
HTH,
