Network install of Adobe Digital Editions

I work for the public school system.  We are being requested to deploy Adobe Digital Editions for reading digitial books.  Last time I looked at ADE, about 2 versions ago, it was not possible to deploy this over the network easily.

Now I am being re tasked with this.  Is it possible to deploy this software over the network, with a silent install?  It must be hands free.  I have up to 30,000 computers and i'm sure half of them will need it at minimum.  I see nothing related to ADE 4.0 and deploying it so please help me out and let me know what the deal is.

thanks,

Noah
