unattended deployment of VI packages

I would suggest to implement a possibility to install packages unattended.
This could be useful if you have to setup lots of computers with the same libraries. If a unattended way was provided, this could be put in scrips etc.
Especially in our case this could be a reason why we cannot use VIPM. I created a *.vipc file and imported them manually. This worked very nice and easy but I am not willed to do this on all of our computers. A in my opinion easy and usual approach could be to put the functionality in a command line argument. I.e.:
VI Package Manager.exe /addLibrary "C:\library.vipc"

I know that there is the VIPM API. The problem is, that this is usable with the pro version only. To install the pro version on all of our computer would be too expensive and never needed any more after this step.
