I've been working on a mobile project for Capespan. This application is being used for the mobile inspection of containers as the are unloaded from ships, lorries and planes.

I'm very proud of this solution as its one of the first I've been involved with that uses photographs taken on the mobile devices as an important element of the quality recording process.    It all works nicely over the Internet using GPRS and WIFI using SQL Compact merge replication.   The added complication is that the back-end ERP database is in Oracle.  So not only do we have to replicate from SQL server to SQL Compact (on the devices);  but also from SQL Server to Oracle.   All of this replication is of course bi-directional.
