with IPB i think alot of people are kidding themselves if they think ipb will be continue it's free trend, right now they're taking advantage of market instability due to the fact vb3 shipped late, but if this wasn't the case i assure you that they would've announced the end of free ipb-ness a long time ago, however i bet they'll continue to host free boards, as that's quite smart especially using the google add scheme, great business sense
as for the the zach/link team, it should be good we should have a few more teams however been that theirs now three of you, where are your products
