WMPUDev membership to a sub-domain

I have a WMPMUDEV subscription for my website (centerforhistory.org)...does this 'subscription' apply to other wp installations on sub-domains of centerforhistory.org? i.e. I have a sub-domain, heritage.centerforhistory.org, and I would like to utilize my wmpudev subscription on the wp installation I have on that sub-domain. Is this possible?
