Deployment Utility or Import Package?

In reference to the question raised in this thread
http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=1460591&SiteID=1

Since I'm not able to create a deployment utility, when a config file is shared among multiple packages and also I cannot get the permission from Sys Admins to use Env. Variables I'm struck.

Now I'm thinking of importing the package to Sql Server from the file system. Is there any caveats in this approach? especially regarding the config files?

Also, do I need any special permissions to view the Integeration Services node in Management Studio? We are using Integerated Authentication, neither do I'm able to run sp_start_job sp in the msdb database.

You might want to look at DTUTIL for deployment. It's a little more work than just building the project in SSIS, but it is more flexible.

With the config files, you just need to be sure they are accessible from the package once it is in SQL Server.
