I don't think vbPortal actually modififies any of the vB tables in the database. Yes it adds many of its' own, but then again any portal package will do that; Nuke, PHPNuke, PostNuke, and PHPWebSite just to name a few.
Yeah there are going to be some "re-hacking" required after a vB upgrade but again thats no different than any portal add-on or for that mattar most hacks.
I would wait until wajones tests a vB upgrade with vbPortal and releases upgrade instructions. I'm sure it won't be that difficult! And vbPortal is more than just a news front end. Sure it does news, but also has a nice system for maintaining downloads, links, as well as 2 excellent photo gallery add-ons and some other really cool things. Don't take any of our word for it, visit some sites using vbPortal or any of the other portal add-ons for that matter.
