Oleksiy has been working on a TCP transport for the new Web Services Stack (also see the entries filed under WebServices tag). The main benefit of this transport is within the enterprise; for example, one can combine this with Fast Infoset and use a stateful approach to the connection and then WS-\* messages can be very small and fast as the common vocabulary is not resent across messages. Initial benchmarks look very nice in situations like those needed for PlugFest Interoperability.
All this is now in GlassFish v2; some more details at Oleksiy's blog.
