hi Sameer,

yes you can - all source code is available under Apache license (Version 
2) which is one the allows you to whatever you want with the code as 
long as you follow minimum requirements described in license, find more 
information about it here: http://www.apache.org/licenses/

did you check WSIF examples and documentation?
http://ws.apache.org/wsif/wsif_samples/index.html
http://ws.apache.org/wsif/developers/how_to_provider.html

i do not know about a need for new providers (somebody may still reply!) 
however i think there is a need to improve support for asynchronous 
invocations that use something like WS-Addressing and allows delayed 
replays (one-way request triggers one-way response correlated to 
original request by message-id) instead of JMS. however doing it 
requires changing WSIF internals so I am not sure if it is what you want 
to do?

i do not know any example of WSDL for aync. services. what kind of 
service do you want to use with your service providers?

here is list of services (all are quire simple request-response) that I 
use for testing with WSDL and parameters that tends to work for me - 
starting with google of course:

                                "0", "10", "false", "", "false", "", 
"latin1", "latin1"});
