+* implement topic-xmlschema
+* Modify totemsrp to allow dynamic definitions of the ring counts

+* Investigate always-on flight recorder

+Ideas for future releases (3.0+)
+--------------------------------
+* topic-netmalloc
+* doxygenize include and lib directories.
+* re-evaluate using libtool to link libraries.
+* Support for clang as compiler (depends on libtool)
+* reorganize library/headers/code in the tree
+* change and simplify build defaults
+* libtotem cleanup/rewrite
+    * Rewrite totem fragmentation layer
+    * rewrite top level totempg interface
+    * Split fragmentation layer in totem (ie: totempg talks to totemfrg
+      talks to totemsrp)
+    * Add a getopt and setopt feature to top level interface to allow
+      runtime configuration of the interface
+* Improve cpg - opaque data in callbacks (client stores data about
+   itself, every node can access them), permissions (read only/read
+   write/ some application may disable listeners) - Probably implemented
+   as extra user space library on top of normal cpg
+* Better statistic - histogram
+* totem multiring
+* load balancing over different speed links in RRP
 
 We use topic branches in our git repository to develop new disruptive features
 that define our future roadmap.  This file describes the topic branches
 the developers have interest in investigating further.
 
-targets can be: whitetank, needle2.0, needle3.0, or future (3.0+).
-Finished can be: percentage or date merged to master.  Once in a shipped
-version, please remove from the topic list.

-Description:
 Currently our RDMA code uses librdmacm to setup connections.  We are not 
 certain this extra library is needed, and may be able to use only ibverbs.  If
 this is possible, the totem code may be more reliable, especially around
 failure conditions.

-target: needle2.1
-Description:
-Totem has many copies involved in messaging which we would like to investigate
-removing.  Our goal is to deliver wire speed performance for rdma networks,
-and if this can be achieved by our other topic investigations, we may not
-further investigate this topic.  The basic idea of the topic is to handle
-message assembly/fragmentation in libcpg, and have totem be responsible for
-sending these pages that are shared via posix shared memory.
