How awesome would it be, If you could:

1. Copy paste all the WSP’s that are installed in your farm into one directory
2. Run a PowerShell script to unpack the content:

3. Have all the assemblies that are inside the WSP packages checked by SPDisposeCheck:
   http://tomvangaever.be/blogv2/2012/06/run-spdisposecheck-on-all-assemblies-in-a-specific-directory-with-powershell/
4. Create one report by using this script to aggregate all results:

In order to use this script, you need to have SPDisposeCheck installed on your machine, please download the free tool from here.
