Hey guys.  I'm working on a Document Management tool written in Silverlight using the MVVM pattern, and I was wondering if you could point me in the right direction for how to handle transmission of large files to and from our document repository.  The architecture and methodology for accessing documents is as follows:  A power user has access to a number of UNC paths where all the docs are located and when the user/client needs a doc, Silverlight is the interface he/she uses with a set of WCF services sitting between the client and the docs.  The problem I'm having is downloading and uploading files > 30MB in size.  I assumed it was an IIS config or Web Config setting, but I couldn't find anything.  Anyway, I know this was a mouthful, but any help would be much appreciated.
