Burn the PDF on a CD and keep this as your digital copy. When you share the
CD, only one person has exclusive access to it.
If you place the PDF in a shared area (networked drive, etc.), you are
allowing all who have access to the shared area the same level of access at
the same time.
Another solution would be to offer a higher priced site license, for cases
where multiple programmers wish to share the PDF. But that may not fit with
the way Dave and Andy wish to sell their work.

So what's the digital equivalent of leaving your book on his desk for
a couple of days?

How long will it takes them to drag it from the CD onto their desktop? Very few people will have the time or inclination to photocopy a book (outside of university students that is) so the loan of a book very rarely results in the creation of a fresh copy. But a PDF? It will take no effort at all to copy and people will probably do it just to get your CD out of their drive and get it back to you before you start to nag them for it.
We do have site licensing plans, and have used them for our other books. Just drop us a note if interested 
Cheers

I just placed my order, and would love to have the dead-tree copy
signed. Barring that, I might even settle for a PGP signature of the
PDF version, so long as I can still say my copy is "signed".
