Yes.  I ran multiple server instances and could shut one down without the
others noticing.
I have deployed individual fixes to WAS 3.5 and 4 without ever having to
shut down the server instance.  If you chose to do it manually by copying
JSP/servlets into the WAS file system it can be a chore, but you can readily
write a script to do it, even in CL.

There are those who say that requiring a manual deploy is the sign of a
'standard in progress' and I might just agree with that assessment.  But I
just wanted to let you know that it is possible to deploy a bug fix without
disrupting  the folks on the other side of the glass.  My guess is that
vendors will fill in the gap that the J2EE folks left in the process.
