integrate between vbulletin & phpnuke!!

first of all ,
i think it is the time to integrate between vbulletin & phpnuke
,
we know there is something called vbportal
but

php nuke is the master of all portals
and we a lot of sites depend on this kind of scripts

i wrote message to FB for begining in integrate between phpnuke and vbulletin
http://www.phpnuke.org/article.php?sid=2151
we get some questions :

is the integration will be in the unprivacy status for vb roles!!?
and
another question
why some programers dose not give this idea some trying?

i use phpnuke and phpbb and there is integration between them occur and they are now in the beta version!!

i do not like vbportal and please do not talk about here !!

i just ask to integrate between vbulletin with the great phpnuke

just to get the same users in the phpnuke and vbulletin



phpnuke has large numbers of addons and modules

vbulletin now is in the top

and it is the time to begin integrate between them

any comment!!
