CKEDITOR with pyaspell

We are using Pyaspell in our product and I need to integrate this with CKEDITOR . How do I do this?
For example tinymce is very generic with spellchecker plugin - as simple as - you can mention which URL to use for ur service side processing and it expects a JSON result .

tinymce.init {
spellcheck_url :/cms/spellcheck.py

}

Does CKEDITOR work in a generic way or do we have a different plugin for spellchecking ?

Please let me know .
