 Shortterm:
 
-- Rotating logs
+- Clean up configuration setting -- just need to rethink flags used, storing
+  of variables and possibly move to file-based configuration.
 
-- Set default charset
+- Rotating logs -- have a check on start for a file-size, rotate out if the
+  file is too large. Possibly checks during run-time too?
 
-- Finish inline shell scripting support
+- Set default charset -- need to think about implementation here...
 
-- Allow setting UID+GID via username string
+- Finish inline shell scripting support -- current thinking is to either
+  perform a C fork very early on, or create a separate modules binary, and
+  either way the 2 processes interact via some IPC method. Could allow for
+  other modules too.
 
-- Fix file cache only updating if main gophermap changes (but not sub files)
+- Allow setting UID+GID via username string -- not hard to implemenent, just
+  a lot of code and didn't want to make things to heavy too early on.
 
-- More fine-tuned handling of OS signals
+- Fix file cache only updating if main gophermap changes (but not sub files)
+  -- need to either rethink how we keep track of files, or rethink how
+  gophermaps are stored in memory.
 
-- Improve autogenerated policy file sending
+- Improve autogenerated policy file sending -- need to rethink the worker +
+  response logic.
 
 Longterm:
 
-- TLS support
+- TLS support -- requires a rethink of how we're passing port functions
+  generating gopher directory entries, also there is no definitive standard
+  for this yet
 
-- Connection throttling + timeouts
+- Connection throttling + timeouts -- thread to keep track of list of
+  recently connected IPs. Keep incremementing connection count and only
+  remove from list when `lastIncremented` time is greater than timeout
 
-- Header + footer text
+- Header + footer text -- read in file / input string and format, hold in
+  memory than append to end of gophermaps / dir listings
 
-- More closely follow GoLang built-in net/http code style for worker
+- More closely follow GoLang built-in net/http code style for worker -- just
+  a neatness thing, maybe bring some performance improvements too and a
+  generally different way of approaching some of the solutions to problems we
+  have
