The problem is that a Delta List is a later workflow stage to PDF, you can't go back to vector and jpeg image compression. I think of it as a series of contones and bitmaps that the screening tower can apply screen to, the file sizes tend to be big.
I used to screen dump from Delta Document Viewer occasionally . I guess you could set up some form of VNC/VPN link.
Kodak Matchprint RIP will accept Delta Lists as a File Format to create an Inkjet proof its very good for spot colours.
