Parallels Tools License Coverage

Hello,

I'm building a Linux Virtual Machine for a company and they're running Parallels on Windows XP. One of their requirements is to have Parallels tools installed on the VM. My question are :

1. Are Parallels tools tied to a specific host machine. Meaning, will i need to install Parallels tools on the VM running on a Windows XP host? Or can i do it on any host machine OS.

2. Parallels tools license - The company has a valid Parallels license. Would they be able to provide me with the Parallels Tools image to install on the VM? Or does this violate any license agreements? If this violates license agreements, what options are available to install Parallels tools on the VM to provide to them?

Any help would be greatly appreciated! Thanks!
