I read another article recently about using an iFrame to refresh portions of the current documents structure without refreshing the entire page. This led me to wonder: using this, couldn't you post the text of a 'currently being worked on' textarea, like the one I'm typing this entry into, to a server side spell checker, styling misspelled words as they're typed like the M$ Word spellchecker does? I think you could. Now as soon as I'm not so tired and have a little ambition, maybe I'll try it.
You probably wouldn't be so tired and out of sorts if you hadn't listened to those same two White Stripes CD's for so long. ;)
I'm the devil.
