Single ITS server, multiple ERP

Hi Guys,

After a little advice as to wether a standalone ITS (on 6.40) can link to mulitiple (3 in this case) ERP 4.7 instances. The scenario is I need to look at a way to get WEBGUI access to all three system... is this possible or do i need three ITS servers for for each instance (or run three ITS instances on one physical machine?)

Cheers!
