Re: Various newbie questions

Wolfgang,

I have been away from the project for some time, but can answer some of
these..

No not all implemented yet.  Yes DCOM would be windows only.  We were
calling this abstration GNU RPC.

Reinhard or Johannes can readily answer this.

I do not believe there is formal documented way of yet, but yes.  You
could extend or create new widgets in existing clients.  Just those
extensions would not be guaranteed compatiability with GNUe official
applications and no concessions would be made to prevent breaking them in
upgrades per say.

The native windows and gtk2 interfaces were fairly functional at one time.
 The curses interface was up and running, but not feature complete.  The
Qt interface was in a similar state.  The HTML interface has had many
iterations and had working code, but has always been far from complete.

All depends on how you write your applications.  GNUe Integrators focus
was to automate feeds from other systems.  Certainly this is supported in
the architecture, but largely will be dictated by the application
architect.


Hope that helps.  Sure others will chime in.
