Re: Howto access project version programmatically within application
Agreed.
I filter-copy a properties file with the following:
project.name=${project.name}
project.version=${project.version}
build.date=${build.date}
...
Then I can load this file and have at it.

Re: Maven - offer anything for runtime?
You can also use the maven-enforcer-plugin to identify dependencies that attempt to bring in older versions of transitive dependencies.

I have to be godlike to know the transitive dependencies and what libraries they use, and inspect my local repository, find out all dups of everything, find out which top level dependency needs it and go exclude this.
