I can understand the word document problem (there are very good
reasons not to use this as a saving format, but almost everybody
does it anyway because it's convenient), but the executable
binaries and package libraries puzzle me.  Either you can rebuild
these from source, in which case you don't need them under
source control, or you got them from somewhere else and your
developers shouldn't be arbitrarily changing them.  Well, there's
other alternatives, but they're rare these days.

Can you get your developers to check their mailboxes more often?
Besides, I'd think they'd be able to figure out that somebody
was working on a given file and coordinate, even given multiple
messages.  (I'd hope so, anyway.)

Not without doing some serious rewriting or switching to another
system.  Have you looked at Noel Yap's patches at the Renegade
CVS project on Sourceforge?  He's added some functionality
to the "cvs edit" system which makes it closer to being a lock.
