How do I monitor concurrent usage?

We do not install any metering software with the network version. One such program is KeyServer from Sassafras (www.sassafras.com). It is available for both the Mac and Windows platforms. We have special versions of KaleidaGraph v5 and v5.5 that support KeyServer. A different set of installers are needed to gain KeyServer support. Please email support@synergy.com for more information on how to receive this version.
