Hmm, I remember getting excited a couple months ago when some work was done in source to "start work on server re-write".
Because there has been mention going back a few years that someday the server would be rewritten with support for server-client management, multi-user, embedded reader, kitchen sink, etc.
Kovid has said in the past he doesn't keep a firm schedule for his TODO list, but works on things as and when he gets inspired. Here's to hoping inspiration will strike again?
