I don't know about Spain, but here in the U.S. people are trying to stay away from IIS as far as they can after it has proven itself as a big piece of crap time and time again.
Maybe you don't realize this, but IIS+ASP is a _very_ different paradigm than using JSPs (in whatever platform). Arguably a good one for developing web applications.
Regarding AOLserver, yes it does. You can develop in Tcl, Python, PHP and Java for AOLserver. The AOLserver site (aolserver.com) lists some modules for it.
You can embed a Python interpreter in AOLserver very easily with PyWX, and I read that using Python under AOLserver is faster than using it under Apache+PyApache. PHP supports AOLserver out of the box. The Tomcat servlet engine can be used with AOLserver via the nstomcat module. And there's the great nsjavablend, from our own Dan Wickstrom. nsjavablend embeds a Java Virtual Machine in the AOLserver process.
