I have a SQL 2005 database in two locations. I would like to be able to make changes and have them update the other DB on the other side on say Monday, and then have changes made after that on Wednesday sync back to the original.

I know that usually you're doing a replication where you have a master and slave, but would this be possible with a tool or script where you can go back and forth as long as it's not at the same time?

You could do that easily by running distributed queries through linked sql servvers or SSIS packages but it may be slow depending on what you need to do (query complexity), the volumes and link speed.

not sure if that will work for me. This is an application that is using the SQL 2005 DB on the backend so I can't really run the queries myself through SQL....

Then in my opinion your best bet is Merge Replication.
