If the trackback module has its own moderation queue, then things could be easier.

I didn't tried to contact the trackback module author 'cause, when I thought about it, I knew I was going to have little time. My main concern was to finish the akismet module itself.

I have recently changed my day job, and I'm now involved on a really big project that's taking almost all my time. However, I would be glad to make any changes to the akismet module, if that helps implemet a spam filter for the trackback module.

Somewhere else I posted the reasons why I have not used the Drupal repository. It was basically to help me manage support easily (by simply minitoring my own site). Though, I'm tempted to commit everything here, 'cause there might be more room for improvements that I'm not really able to achieve due to lack of time. If that happens, I'll post a notice here and at my site. ;-) For now, I believe I could do small changes to share the akismet API easily.
