* Security requirements
  * App level authentication needed?
  * Are there 3 or more participants in the security domain?

* Transaction
  * Need 2-phase commit?  Oh, ignore this.  I just want to say. :-)
  * 2 or more communication can be organized?
  * Error status transfer?
  * Required reliability?
  * Bulk data transfer (independent 2 or 3 msgs at once) needed?

* Data type
  * Includes binary data?
  * Data complexity?
  * Extensibility?
  * Required language binding?  Only Ruby/Java?

And extensibility in the future.  You might not have to think about
it (YAGNI).

For example, I choose followings for my company projects;

* CORBA between C++/Java
* CSV over HTTP between C++/PSQL
* XML over HTTPS between C++/(I don't know)
* SOAP over COM between JScript/C++
* XML over e-mail between Java/(I don't know)
* SOAP over HTTPS between Ruby/Perl/Java
