You'll probably have better luck getting a vBulletin integration done by someone on vbulletin.org
I'll probably use IPB with D7, but I have about 700 threads on my vBulletin site that I'd like to import into IPB. As much as I'd like to see both a vBulletin and IPB integration done by Boonex, they are going to have their hands full for quite some time with other, standard, aspects of the script. IPB and vBulletin integration will simply have to be a third party integration... at least for now. see more I started a thread about IPB integration in the forums... maybe you can start a similar one fo vBulletin.
On all your other points, I am in complete agreement.
