Yes, most part of the Java world does it, and bloatware like
openoffice do it, yet it's a real disease. And it's becoming a royal
PITA if you discover that for some included dependencies no matching
sources are (no longer) available, or if the included dependencies
have been built from *patched* sources (and the patch is missing).

Show me one expert's argument for this. I don't think there' any
arguments beyond "i'm lazy", "other people do it the same way", "we
don't have a dependency management tool".

Well, I'd do the same as I'm doing currently with CVS: keep an
ivy.xml in the project, check in the code changes of a *delivered*
ivy.xml for each release, and put back an undelivered (i.e. with
revision wildcards in the dependencies) for further development.
This is done with a set of ant tasks.

The concrete method for Synergy/CM would be different and of course
heavily depends on the development model you're using, but I'm sure
it's possible.
