Find active API users

Question

Is there any (easy) way to find out which API users are still active? Or when a user was used the last time?

I just came up with add some logging code in

app/code/core/Mage/Api/Model/Server/Handler/Abstract.php
login()

Answer 1

I ended up adding some logging code. If someone has a better solution, please share.
