Few years ago I wrote a small plugin that took batclient text input,
send it to google translate and printed translated text to another tab.
It was semi useful and funny (because of the quality of some of the
translations). Unfortunately, this doesn't work anymore as Google Translate API
is only available as a paid service.

It would be cool if Batclient/Batmud had in game translation (beyond simple
'word' command) to multiple languages. I think this could make game easier for
newbies and shouldn't cost a fortune if you can make a special arrangement with
some company selling automatic translation software.
