Online spell checking

Hi all,

Bit of an odd one but hopefully someone may have some good ideas! Basically I'm working with a client delivering a cms and they want to be able to spell check the data that they've entered before submitting the content. The won't use a normal browser, as usual they won't move off IE6!

I'm thinking of creating a jQuery plugin to fire the content off to an api such as google's and display the results. However Google's has limitations of 10 words per request and a max of 1000 a day which is far too small. Does anyone have any suggestions of any other apis or any other way to implement this?

Thanks in advance
