+(Not in any particular order, and

+* general performance improvements, but without relying on
+ XS or compiled code any more than we currently do.
+
+* mailmap support (same as git) for remapping expired email addresses
+
+* POP3 server, since some webmail providers support external POP3:

+ Perhaps make this depend solely the NNTP server and work as a proxy.
+ Meaning users can run this without needing a full copy of the
+ archives in a git repository.
+
+* HTTP and NNTP proxy support. Allow us to be a frontend for
+ firewalled off (or Tor-exclusive) instances. The use case is
+ for offering a publically accessible IP with a cheap VPS,
+ yet storing large amounts of data on computers without a
+ public IP behind a home Internet connection.
+
+* TLS support for various daemons (including STARTTLS for NNTP and POP3)
+
+* NNTP COMPRESS extension (see innd)
+
+* Combined "super server" for NNTP/HTTP/POP3 to reduce memory overhead
