Team collaboration services on the Internet are many and varied – Feng Office is one I haven’t heard of previously:
The team workspace itself offers the standard array of capabilities – notes, email, contacts, documents, tasks, and web links, along with a dashboard overview.
Feng Office is offered as a hosted service, or can be installed locally.
There is an overview tab, that shows upcoming stuff. It pulls in material from multiple workspaces, thus giving users a snapshot view. This is really important.
There are no offline capabilities, as far as I could tell, no was there any mention about access from mobile devices like iPad or iPhone. Yes, you can access them via a browser, but there is no Feng Office app as such.
