I think this is why 'ESBs' have been successful - they wrap the async
plumbing (needed for scalable integration) behind a sync facade that
joe developer sees as 'request response'.  Then the transaction model
- whether more local TX style or full-on DTX style - can be set as a
configuration choice.  (If you do your ESB right...)

In my own view, distributed transactions are to be avoided whenever
possible.  But providing simple tools to enable that in practice, can
be a challenge.
