Prevent user from copying/pasting messages in Spark

I’m in the process of evaluating an instant messaging project where we are integrating Spark. But one requirement is that the user cannot be able to copy and paste any of the messages in the message room. Can this be done in Spark? Is there a feature that prevents the user from copying/pasting messages? If not, seeing that this is open source, can it be modified to do this? I’m not a Java programmer, but need to know so that we can ask someone to implement this feature for us. Thanks!

a quick google search on disabling copy/cut/paste in a swing application points to this being possible.
