Two servers question

[muzikmark]

Hi all.
I LOVE Subsonic. My friends and I thank you!!!

Quick question.
I have Subsonic Premium on my laptop server.
I would like to install it on a second laptop on my wifi network.
Do I still need to pay again for the Premium service?

The main reason I want to do this is because the second laptop is the one I hook up to my stereo and surround sound.
I would like to use this one with the isub remote app in "Jukebox Mode" so my friends and I can queue songs while we're hanging out.
Most of them have the app on their phones.
The second laptop has the bigger screen and nicer sound & graphics but I don't want to make this one my primary server because it is not on all of the time.

Thanx for any help!!
