[Observium] Contact for subscription and another question

Hi, Just a quick couple of questions. I've been off the list for a bit. - I want to purchase a sub for Observium, but being public sector we have some weird ways of paying for things. Who should the purchasing department contact? - Does the WMI stuff work for exchange? I send a mail about it a while back, and it certainly would be useful to us, or at least pointers to how the wmi framework function would be good so I can do some scripting myself. Any ideas if the wmi scripts work for 2010 exchange - I've only seen anything done via powershell there..

Thanks Andy
