Garry,
The quick answer is "Yes". I have been on teams in the past that have done
this with Java using various libraries (i.e. Java clients consuming .NET/WSE
web services). Presumably, any language that supports the creation of SOAP
messages can interact with WSE so long as they create the various XML
elements according to the WS-* specifications. However, it has also been my
experience that no other (current) language/IDE makes it anywhere near as
easy to implement as does VS.NET.
