Groupware URIs

We are working on a groupware application. In this
application, a groupware user always uses the groupware
server, in which this user is registered. But the user can
see groupware objects in other groupware servers. Since the
user interface is web-based, the users use URIs to get to
groupware objects (=forums, contributions, users).

These URIs are constructed by combining the URL of the
user's local groupware server, with the URL of the object.

On server there is a forum named free-speech.
On server, a user is participating in this forum.
This user will then use the following URL to get to this forum:

If a user at access the same groupware object,
they use the URL

Thus, there are different URLs for the same groupware object,
depending om where a user's local groupware is. But it would
be nice to have some kind of designation of an object which
does not change this way. We have done this by specifying
a new URN or URL scheme named "gw" (for groupware).

Thus, in the above case, the gw URL for this groupware object
would be gw://

Ordinary web browser will not understand gw: URIs, unless
they are helped by a directory which tells them which is
the local groupware server for that user. Knowing that,
they can construct the right URL for this user, i.e.
convert gw:// to, for example,

Question 1: Is this the right way to go?

Question 2: The "gw:" URI scheme, is it a new URL
scheme or a new URN scheme?
