I am interested as I am writing a spellchecker and the data should come from wiktionary
--- the only problem with pulling data from the wiktionary is how trustworth is it? i spell stuff wrong all the time, and if i put an incorrect spelling of 'sincerly' into the wiktionary the spellchecker would consider it to be correct? I do like the idea thought, i know loads about web services and eventually would like to write some plug-ins for other applications that can search the wiktionary for thesarus words, definitions, translations, etc.
the other question about the spellchecker would be, should you be able to download 'spellcheck' files so it can be run locally? this might be an option so that smaller devices like PDA's can leverage the wiktionary and run local look-ups?
The spellchecker could also be used in reverse, so when people mis-type words they are searching for, the spellchecker could give you something like ' NO RESULTS FOUND, DID YOU REALLY MEAN: ...'
