+Only reason I can remember (a year and a half later) of is that it\r
+seemed like the basic illustration of concept would be a saturday\r
+morning's project. In retrospect, I think the main issue was that I was\r
+trying to figure out how history would be kept. By using git, though,\r
+your idea would be that we get history for free, right?\r
+\r
+I think my format was:\r
+\r
+    <TIMESTAMP>    <MESSAGID>     <TAG>\r
+    12345          foo@bar        to-fix\r
+    13456          bar@foo        feature-request\r
+\r
+But using git would get us timestamps for free too, I guess.  And if we\r
+get rid of timestamps, then we just have dumps. So what we would really\r
+just need is a thin namespacing layer in some scripting language on top\r
+of git? I.e., all we need something to just keep different dumps in\r
+different namespaces, so that when I pull your dump, the tags come in as\r
+`bremner/to-fix` (or whatever our separator is), and then when I dump\r
+all `bremner` tags, it removes the namespace and puts it in\r
+`bremner.tagfile`.\r
+\r
+One rather obvious thing that I discovered: processing dumps and\r
+restores from the ui is pretty slow, because you have to output a huge\r
+file, and then find the tags in your preferred namespace. So using\r
+either the library or the bindings would probably speed things up quite\r
+a bit, by only dumping the tags you care about. Which means it couldn't\r
+just be a shell script: it would have to be c/ruby/python.\r
+\r
+Best,\r
