MySQL EA synched across two networks?

[javelin5]

We are running the coporate edition with MySQL.

Due to customer requirements we need to share part of our model with them (Requirments through use cases[robustness analysis]).  Our software baseline is on a seperate isolated network.  We would like to do a one way synchronization of the model through the use cases on the isolated network.  On the isolated network we will be doing the rest of the design, sequence, class, state, and activity diagrams.  Also we will want to link the classes to the use cases with realizations.  This would occur any time changes in the mentioned sections occur (probably at most once a week).   We don't want to lose any of the connections when we synchronize the two databases.  What would be the best approach to this? (XMI export, SQL dumps, etc.) What might be some of the problems that may be encountered using the suggested approach?

I think I answered my own question.  Looking at the database tables and doing some thinking led me to the conlcusion that the XMI export would be the best way to do this.  

Searching through the board led me to a concern over this.  There was a message half a year ago or so that basically said they were losing objects doing this type of synchronization.  My question is anyone else having this issue?
