We just chatted with Meebo co-founder Seth Sternberg and he told us that he just closed a deal with Netvibes to create a Meebo module for fully integrated IM access within the Netvibes site. The Netvibes blog has some screen shot here and more info on the functions. Seth had no comment on the financials of the deal, but its a significant partnership for the IM startup. And the Meebo team figured out sometimes tricky cross-scripting so the Meebo module tab lights up when an IM is received. Cool!
