+<h4>Making Blixem independent of Acedb:</h4>
+
+<p>There is some argument to support removing blixem from acedb altogether as when
+it is compiled into a stand alone program it has no acedb database dependencies. The amount of work
+required to do this is not trivial however as blixem does use the build system and a number of types, packages and
+functions from the main acedb libraries. An initial survey of the code suggests
+that at least the following would need to be replaced/modified:</p>
+
+<ul>
+  <li><p><b>Makefile:</b> either replicate the acedb make system or introduce autoconf.</p>
+  <li><p><b>Basic Data Types:</b> replace:
+      <ul>
+	<li>BOOL
+	<li>SMapMap
+      </ul></p>
+  <li><p><b>Compound Data Types:</b> replace:
+      <ul>
+	<li>Array
+	<li>messXXXX system
+	<li>memsubs functions, including the handle package
+	<li>freeXXXX routines
+	<li>Stack package
+	<li>AceIn/Out package
+	<li>Dict package
+      </ul></p>
+  <li><p><b>Miscellaneous:</b> There are a number of common subroutines/facilities in acedb
+      that would need to be replaced:
+      <ul>
+	<li>externalCommand(), findCommand()
+      </ul></p>
+</ul>
+
+<p>The scope and diversity of this work implies that it will require a month or more of effort
+by someone who understands how these packages work, for someone who doesn't know acedb
+the work is likely to run into 2 to 3 months.</p>
