It just felt soo long since I had last hacked on anything xmlrpc-related, and some part of me was looking for an itch to scratch.
Luckily today a request for help via email set me on a hunt for blog posts / forum posts / mailing list messages where complete newbies ask questions about the phpxmlrpc lib not working for them. Of course they post there instead of the correct mailing list because in fact they have trouble setting up their favourite php application. Heck, they probably do not even know what phpxmlrpc is.
To make a long story short, I ended up looking at the code of a poorly-written dotproject xmlrpc plugin, and wondering why the mantis bugtracker has such a nice and clean soap interface but has no xmlrpc one.
And since it was late evening – the best time to code, when there are no distractions coming in over the phone or chat or email – and home alone, I just sat in the front of the keyboard decided to put and end to that last shameful situation.

For everybody who needs it ot just wants to test it, here it is: the Mantisconnect XMLRPC Interface, rev. 0.1
