Any chance Digital Compies might be made available either in advance or down the line?

Monte Cook put out his massive Ptolus Campaign setting in PDF chunks prior to printing... I purchsed both Digital and Paper copies and use/used both extensively (the digitals make for great travel reading/prepping, which comes in extremely handy as I travel quite a bit... relying on the internet to keep my gaming going). Each PDF was tailor watermarked to the buyer (through Drivethrurpg.com I think it was) to hamper piracy.

Just a thought/wish!
