Right.

You're free to write your own.  eCos suits my needs quite
nicely.

Firstly, there might be a reason for that.  We're not stupid,
you know.

Secondly, I have no idea what you mean by "pattern oriented
architecture" can you point to a description?  The things that
Google found were either describing ways to fail:

   Pattern oriented architecture - A trend that's found in
   systems created by architects who've recently read and
   digested books on architectural patterns and come to the
   conclusion that implementing patterns (such as
   front-controller, etc) is the key to a successful
   architecture. Rather than determining if common patterns are
   appropriate, and picking the most suitable one, all patterns
   that can be applied are done so, on top of one another,
   creating an entangled, schizophrenic system.

or were marketing buzword-bullshit:

   A standards-based, pattern-oriented architecture that follows
   industry best-practices assures that the NEFS will fit right
   into your development environment.

People have been saying that for 10 years.  I stopped paying
much attention 5 years ago.  Java requires MASSIVE amounts of
storage compared to eCos.

OK.
