It would be a nice feature if the developer id could be mapped to the name attribute in reports and e-mails, i.e. reports would contain the full name rather than the svn user, ref. the snippet below.
<developers>
<developer>
<id>t527560</id>
<name>Kristoffer Moum</name>
<email>kristoffer.moum@arktekk.no</email>
</developer>
