Sure but that depends on how familiar you are with linux. I gather the reason no one has answered you sooner is because if you are a linux newbie, the instructions can and will be lengthy. I am going to assume that you know how to create directories and add permissions. Now, after knowing that much. You can create a "users" group that has all the users on your system as memebers given permission to your limewire installation. Here is a brief example
(I am logged in as newbie):

~/ $ls

.
..
limewire

~/ $chown -R newbie.users limewire

Create a symlink to the limewire binary to /usr/bin.

~/ $su -c "ln -s limewire/LimeWire /usr/bin/limewire"
password:
~/ $

Now all the users can just type "limewire" (without the quotes) to run and use limewire.

~/ $limewire
