(I'm going to guess my way across the language barrier a little - is Groove as big in Brazil as it appears?)

- There's already some neat Outlook integration: pulling a mail thread into a Groove shared space so you can actually get together to nail things down. The same sort of functionality is available for Lotus Notes in version 2.1 (real soon now). The Outlook integration is actually quite straightforward; it uses the Outlook APIs in a standard COM addin, which creates a temporary .GRV bootstrapper file, which gets you a shared space.

- Our web services work will make it a lot easier to connect non-Groove systems -- Java especially -- to Groove shared spaces. Going the other way, we're doing a lot of work around Sharepoint (with WebDAV and some other stuff), and of course there are several of us now blogging, and very interested in the intersection of Groove and blogs. But that hasn't reached "product" yet.

- The forms tool is pretty good. Extremely flexible, especially when you start scripting it. (When I saw the first prototypes I was sceptical, but Rob proved me very wrong indeed). It very definitely has a future. If you're looking for a quick and simple way to add some structure into the way your Groove shared spaces handle data, this is it. I think in fact about 80-90% of custom enterprise Groove applications can be built with Forms.

- I honestly don't know what the future holds. I could guess: more tools; more services; more integration. But a lot of this will be determined by what customers need and ask for.
