    Any thoughts on those?
    Materialized Views have to be created over a dblink - in this scenario - which I think defeats the purpose - I have to agree that it looks like a very atractive and elegant solution.

    In regards to Transportable Tablespaces, I think you can generate a Transportable Tablespace only on Enterprise Edition while it can be imported into any edition; plaforms with different endian format would require some extra setup synchronization like compatibility_level I think. If laptops are not running Enterprise Edition it wouldn't be possible to send data to the central database this way. Also, source and target database have to have the same character set and national character set configuration. I have the feeling this solution keeps adding potential issues to the solution.
