Right, there's a per-user repository at ~/.m2/repository .
Without any change to lein, its "install" subcommand will place a jar for the
current project within ~/.m2/repository . The jar can be used from there in
other local projects. Here's an example:
% cd <project-A-dir>
% lein install
[...]
[INFO] Installing ./projectA-1.0.0-SNAPSHOT.jar to
~/.m2/repository/projectA/projectA/1.0.0-SNAPSHOT/projectA-1.0.0-SNAPSHOT.jar
% cd <project-B-dir>
% lein install
[...]
[INFO] Installing ./projectB-1.0.0-SNAPSHOT.jar to
~/.m2/repository/projectB/projectB/1.0.0-SNAPSHOT/projectB-1.0.0-SNAPSHOT.jar
% cd <project-C-dir>
% cat project.clj
defproject projectC "1.0.0-SNAPSHOT"
:description "FIXME: write description"
:dependencies [[org.clojure/clojure "1.2.1"]
[projectA "1.0.0-SNAPSHOT"]
[projectB "1.0.0-SNAPSHOT"]])
% lein deps
Copying 3 files to <project-C-dir>/lib
% ls lib
clojure-1.2.1.jar projectB-1.0.0-SNAPSHOT.jar
projectA-1.0.0-SNAPSHOT.jar
This appears to meet Konrad's original specs except (depending on the intended
meaning of "repository") for:

I would argue that the ~/.m2 repository is nearly as easy to work with as any
other local, on-disk scheme one might envision and has the benefit of working
with any maven-compatible tool.
It also works for arbitrary jars one may have on disk (acquired from any
source) via:
