Multi user install on Linux Ubuntu

I installed Spark (with help from thread “Installing Spark IM Client in Ubuntu Linux”)

And I can run it from my console.

I would like to install for the other 20 users on my server. And, ideally, put an icon in my menu, to start like other applications.

Any ideas? And do I need to copy the Spark folder to everyone’'s /Home folder? Or can everyone start the application from the same folder? Is there any documentation on this?

thanks.
