Right, if you're disconnected from the network, that's all you can
do (and it sucks, because if you haven't already checked out the
file you want to edit, you have to "hijack" it, and clearcase deals
with hijacks in a braid-dead way).

But if you're on the network, you can use a snapshot view in the
same way as a dynamic view.  You just don't get a "real-time" view
of the repository and the magic foo.c@@/ directories.  (It has the
advantages that you can take it off the network and still have some
limited functionality; it's faster; and you don't have to run an old
Linux kernel and binary modules.)

So to be clear, I was definitely talking about using a snapshot view
while connected to the clearcase servers.  In this case, you can do
everything you could do in a dynamic view.
