I just wanted to point out that some aspect of a reliability solution
may be reusable in a loosely coupled manner.  For example, message ids.
But a complete SOAP based reliability solution cannot be.

BTW, I just found this, a better description of the infamous "A Note on
Distributed Computing" paper than the paper itself provides (by Jim
Waldo, of course);

  "In particular, we argued that distributed infrastructures must
   present a model of partial failure to the programmer, since only at
   the application level can such failure be dealt with; must deal with
   concurrency issues, rather than leaving them to the infrastructure;
   and must at the application level realize what parts of the program
   are local and what parts are at least potentially remote."
