Afaik you _could_, but it wouldn't be transactional (not a problem for
read-only operations I suppose), you expose yourself to more potential
exception sources (=higher risk your bean might mess up transactions it
partakes in unless the network the socket call is made over can be considered
reliable), and I guess there might be potential problems if the remote end
blocks for a long time or so... It shouldn't be too hard to put together a very
simple test environment to find out, though?
