   |Hi, I've been using the scp example in Jsch with success.
   |I am now wondering if I can use Jsch to encrypt (and
   |compress) arbitrary bytes and Java Objects in the context
   |of my own client-server protocol. Is there an example
   |program that demonstrates this sort of thing?

As you will find in that scp examples, you will get java.io.OutputStream,
and java.io.InputStream for remotely exec-ed process, so you can transfer
any 'fixed size' data including serialized objects.  For transferring
stream (unknown size) data ,you will be able to use put/get methods of 
ChannelSftp.

   |On a related note, I am concerned about opening ports
   |on the server side. If I implement my own data transfer,
   |would I be able to piggy-back on an existing ssh or scp
   |port?

How about using remote port forwarding?
