you seem to be confusing a network administrator whose main focus in life it to help IT actually work (with the first imperative to be that the network remains safe and stable!) with some Operator (eg BOFH) or senior IT director.
A network admin lives in layer 1 - layer 4 most of the time. we dont CARE what email app you choose to run or email platform you use, or groupware. we DO care that it follows specifications and that theres clear documentation about what protocols/ports/etc it needs to run as we need to ensure that things like firewalls and ACLs are sorted out. we care that its not a pile of crock like microsofts load balancing sh*t. I embrace things like BYOD (and have done for much longer than the recent industry hype about it!) - but someone else writes policies on data retention/control etc.
..and anyway...who're you going to blame when things take time or go wrong if its all just some automagic HP software stack (and based on their (and ciscos) historic and current coding and software delivery it IS going to go wrong)
