Can you package something as complex as MSSQL? How long would this typically take with the right knowledge and experience?

We have successfully packaged MSSQL. This can be done in a half hour or so beyond the basic SQL install. We recommend you talk to us for guidance since there is some complexity in the Microsoft environment that can be challenging for a new user to figure out during the creation process. Most of this complexity revolves around the WMI management interfaces.
