Dear All: It is necessary for all cloud office interoperability with each other. Do you think so ? What I want to do,is not to design a product for my own company. I just want to , between all cloud office websites, it can send documents quickly. Such as ,Google Docs can send documents to Microsoft Office 365 quickly, and directly . But now , Google Docs can only send documents using email (SMTP) to Hotmail. So i think HTTP(SPDY) is better than SMTP for transfer online office documents ? So we should suggest ,IBM Docs and Office 365 ,Acobat.com use the same protocol. The second thing I want to do ,all online office interoperability . your know , for native office, an Microsoft Office 2010 document should be open and reedit by an Openoffice.org user , it means native office interoperability. Then for the cloud office, it also need interoperability. So let us do this thing together!As I know ,you all are great man and warmhearted! ?Thanks !
