Afaiu, Spellchecker wouldn't fit auto completion. Auto completion is about suggesting existing terms in the index after you typed, say 'jack'. There are some Lucene strategies on how to efficiently write auto-completion suggestions (I do not know where references are, but just have the 'termenum' represented as some tree, where every node is just one 'letter', you have easy auto-completion possibilities. You also might want to check Solr, they most likely have something for it). However, I don't see the match with a Spellchecker, which goal is 'did you mean', kind of info (it uses ngrams for this, something you don't need for auto-suggestion I would think). Now, another thing is, that how would you be able to 'query' jackrabbit for auto-completion suggestions? You should add your own query extension right? currently, from the top of my head, for xpath you have something like rep:similar. You might have to hook in then rep:autocomplete or something. I don't exactly know how this works out.
