I am thinking of creating an overall facebook connect plugin or a simple comment plugin, in both cases there are some questions that pops into mind:

1- does it make sense to you too to merge/import facebook comments into b2 comments (i think it is simply because i wouldnt want 2 seperate threads per post)

2- how hard would that be

3- what's the most effective way to do that ?

(merging/importing FB comments every 1 hour or so ? and in some way can we make use of cache ? )
