You presume that transactions between web services is a good and possible
thing. Most people think of 2 phase commit when they think transactions,
and I have serious doubts about that. Satish Thatte wrote a good position
paper referencing this, http://www.w3.org/2001/03/WSWS-popa/paper39. One
summary would be that 2PC doesn't for web services.
If you mean long-running or compensating transactions, then I agree that
transaction support will be required.
