Snapshots can be accomplished by copying the entire VM on disk while it
is not running.

You have to power down/suspend/resume VMs individually, but I believe
you can write scripts to gang multiple VMs together.
Workstation has a file sharing system that the other two don't. With
Server I have to keep toggling back and forth between loop back and
bridged because bridged won't work when there is no network connection,
and host-only won't talk to the outside world (I suppose I could set up
routing on the host to NAT for the loopback, but I haven't gotten around
to trying to set that up). VMWare Workstation has a mode to share file
between the system independent of the network setting.
I was going to say that it was a bummer that you had to get esx to
support both host only and bridged at once on a single VM (by two
different virtual NICs), but I just realized I can add an additional NIC
in Server, so I am trying this now.
