-    One problem is that numeric ipv6 addresses on the command line
-    don't work as they conflict with the host:port format for
-    specifying host names.  Fixes for this I can think of include:

+rdesktop now supports numeric IPv6 addresses:
+
+    It checks for two or more colons in an address to decide what it's
+    dealing with so you can now do:
+
+    rdesktop 2001:1:2:3::4
     
-    * have a -6 switch for enabling ipv6 support
-    * change the host:port format to 'host -P port' or something
-    * more complicated parsing of the given host/address
+    without it getting confused with an ipv4:port specification.  I've
+    also followed the square bracket convention used by browsers
+    (http://www.ietf.org/rfc/rfc2732.txt) so if you want to specify a
+    non-standard port with an ipv6 address you can use the format:
+    
+    rdesktop [2001:1:2:3::4]:3390
