Welcome back Mario.
Sorry for the delay. This has been a crazy week; I am going to California for a month, departing this Saturday.
OpenGoo is a lot like OpenOffice, but Web based. That means it should be accessible via a browser, so that no installations and no licenses and no synchronization is ever needed.
That does not mean that several plugins (Eclipse, OpenOffice, MS Office, etc.) could be developed to extend its functionality.
We were discussing just this the other day: Wouldn't it be cool to have some Office plugin that would let you save directly from your desktop office suite into the OpenGoo filesystem? (Eduardo's idea)
