So Google has already launched Google Base which is said to be an eMarket like eBay (screenshots are already available on the web posted by those fortunate enough to log in for once); apparently Google seems to follow SSO (single sign-on) :-) and therefore your Gmail account should be able to log you in. MS also seems to follow the google foot prints and they have their showcase up @ http://sandbox.msn.com. Start.com application seems to be the most interesting product from the showcase typically boasting web-parts feeding off RSSs. Certainly worth a glance......
