Online office suite Zoho one-ups its Google counterpart by offering a half-dozen quick-access gadgets for its Docs, Mail, Calendar, and other webapps, embeddable in Gmail, Facebook, iGoogle start pages, and nearly anywhere.
Zoho’s gadgets use the OpenSocial standard and pipe out as fairly standard XML. In plain speak, that means they can be embedded on web pages and blogs, in iGoogle or any other XML/RSS-friendly start page, and, particularly helpful, as a Gmail sidebar gadget.
As ReadWriteWeb points out, you won’t have to authorise the gadgets separately on Gmail or iGoogle, as the gadgets support a pass-through oAuth. On social networks, the gadget act more like “applications,” letting you choose who to share docs or information with and adding them to your profile.
