gregor: I work for a government organisation and all 3 sysadmins have in depth knowledge of all of those systems, with a specialised network admin who runs the CUCM / Cisco router and switch initial configuration / node installations etc.
Even myself as a regular tech has to have a good knowledge of Exchange, Hyper V / VMWare, SCCM 2007, Commvault Archiving Systems, Windows Server, Papercut, Apple administration (inc Admit Mac) and deployments, as well as the basics of SQL, Sharepoint etc etc.
We also don't get paid obscene amounts, however the experience gained over simply being a "have you tried turning it off and on again" level 1 tech is invaluable IMO.
So therefore I don't find it that far fetched, but one would hope that it's paying AT LEAST 80k lol.
At least I don't have to state times on our internal helpdesk system taken on jobs, but I could see it happeneing one day
