How is this going to compete with Zaplet I wonder. Groove seems more open to partnerships, which would give them an edge since both companies want to be platforms. Will Microsoft want to buy Groove, while Zaplet has Cisco, Oracle and Novell onboard? Will this be a tech fight, with XML/SOAP stuff against Java stuff? Sounds fun.
