--------------------------------------------------------------
I patched a version of the HTTP wagon for my needs based on the current trunk:
https://github.com/codeflows/maven-wagon
You can configure it to use pre-emptive basic auth (with HttpClient 4, based on
the example at
http://hc.apache.org/httpcomponents-client-ga/tutorial/html/authentication.html)
per server like this:
{code:xml}
<server>
<id>your-server-id</id>
...
<configuration>
<httpConfiguration>
<usePreemptiveBasicAuth>true</usePreemptiveBasicAuth>
</httpConfiguration>
</configuration>
</server>
{code}
Can't say if this approach is without its problems, but it seems to work for us
(i.e. artifacts are only transferred once.)
This test case sums it up:

> Key: WAGON-277
> URL: https://jira.codehaus.org/browse/WAGON-277
> Project: Maven Wagon
> Issue Type: Bug
> Components: wagon-http
> Affects Versions: 1.0-beta-6
> Reporter: John Casey
> Priority: Critical
>
> This causes timeouts and tends to cause invalid checksums for anything that
> attaches an observer to the stream or connection (Maven does). It seems that
> the Sun (lightweight-http) wagon sends the first file twice, then caches the
> authentication after a challenge and uses preemptive auth from then on. This
> wagon should probably take steps to approximate this strategy, or possibly
> even improve on it.
> For an example of this, try deploying any artifact to a normal http
> repository (Nexus uses bare HTTP PUT, for instance) with Maven 2.2.0, and
> watch the checksums or logs to see how the transfer takes place.
