I currently have my home Mac mini set to sleep after 15 min and sleep the hard drives.  I use logmein for remote access, but I find direct access to a server is more reliable.  I want to set up VPN, since screen sharing over VNC is not encrypted.  I already have Mountain Lion Server (I use it to remotely manage another server).  I haven't set up any services as of yet because I'm afraid I will lose sleep functionality.  Can anyone confirm this? 
Thanks
