Yes, storing reports locally is possible. However the stored reports will be encrypted, so listing them may not be useful. The de-obfuscation information is stored on your SmartAssembly client (in the map file and database) and so the error reports need to be moved to the client to be viewed.
There is an example project provided with Smartassembly. It should be located C:\\Program Files\\Red Gate\\SmartAssembly 6\\SDK\\Exception Reporting\\4 Via Email
You need to
1) Save the reports using the SDK (using reportExceptionEventArgs.SaveEncryptedReport(fileName))
2) You can then send the reports by a means of your choice.
3) You then add the report to the SmartAssembly databse using the addreport command (http://www.red-gate.com/supportcenter/C ... rtAssembly
4) View reports as normal using the Smartassembly GUI
