I think a cool thing that would go well with the "direct connect" feature is like passworded folders that only people (yourself / friends) with the password can access (if this isn't already possible)

That way limewire could even be used as a connection between two (or more) computers sharing whole drives with each other.. that would be cool.
Maybe this can already be done, but I'm new to limewire, so I thought I'd throw in my two cents.
