Can I create a new comment type?

Taking a quick look at comments.php, I can say – using custom comment type is so far legal, however I didn’t played with this yet but you can, and post back with your results if you found any illegal stuff in this.

I found on codex the get_comments() function is accepting comment type as argument, so you’ll not be having any problems with accessing comments of type foo.

Also other functions are looking clean to use with custom comment type.
