I'd like to be able to select a collection of nipkg files in e.g. Windows Explorer and use NIPM to install them in the correct order based on their interdependencies.
If I create a local feed and add that, then NIPM will allow this via selection in the Packages tab.
However, there doesn't seem to be a method to select multiple files that are not in a feed using a GUI (Windows Explorer or NIPM etc).
VIPM has an "Open Package File(s)" menu item that fills this role.
I think (although I didn't test, because I didn't consider this when I was running into this issue) that using "nipkg.exe install A.nipkg B.nipkg C.nipkg" would work for this, so there is a workaround. I just didn't consider it earlier...
