ah but think of the slowness involved in mirc sockets and stripping out the XML, etc - instead you could get an associative array from PHP and merely loop thru it.
ie start com object
push query to it
pump out results.
So much of the complexity would be hidden behind apis.... it would mean powerful scripts with simplicity - plus PHP's XMLrpc library would be uber optimized so would have minimal performance impact.
It would also mean something like PHP's ADODB is easy peasy - any database, anywhere, right now.
The only thing more I'd ever ask is improvements to the mirc COM calls to be able to call member functions of objects and stuff. (ie application.internetexplorer.window.document.yaddayadda)
and WHEN we have that, we have the world in our greedy little scripting hands.
