Flash MMORPG Possible?

I have been playing Dofus lately and am fascinated that it was made in Flash. I never though a MMORPG would be able to be made in Flash (of course it is not only Flash. It uses a DLL file as well as a XML file). But all that is in the XML file is


 [-](http://kirupa.com/forum/#) <config>
     <play host="**lang.dofus.ankama-games.com/files/**" /> 

    <delay value="**500**" />  

    <rdelay value="**3000**" />  

    <rcount value="**10**" />  

   </config>

I checked that website out and it shows the directory structure which has some folders and some files. Could anyone please help out? I heard you need a pre-compiled socket server. Are there any free ones? If so could anyone please provide a link because I am having trouble finding one.
