Any thought to being able to expose WPS as an Operation? One of the
things I am looking forward to is getting some of our client-side
processing stuff available in uDig as Operations, and a WPS can be
considered a remote instance of an Operation. Along with a chaining
UI for operations, this starts to get very cool, with client-side
operations interacting with server-side ones, all as peers. Sort of
extends the uDig "a layer is a layer is a layer" paradigm into the
processing side as well: "an operation is an operation is an operation".

I think so, let me try one:
1. user adds a WPS url to a preference page
IDEA: Preference Page
2. Create a Web Process context menu for WFS FeaturesType (am I
correct
in understanding that WPS can only be used when chained with a
WFS? Or
can we upload GML as to the WPS and get an answer back?)
IDEA: Context Menu Contribution
3. A dialog pops up where the user can choose what process to
"Execute",
uDig creates a temporary layer to "catch" these features as they
come back
IDEA: Dialog
4. WPS goes chunk chunk chunk on the data
5. SPS Cient gobbles up the GML as it comes back, and provides a
stream
of normal geotools features
6. uDig takes those feature and puts them into a temporary layer
as they
are produced.
IDEA: Creating a tempoary layer
7. user can do normal stuff with the produced data, including save it
out to a file.

I'm thinking it could also be nice using WPSs in the uDig workbench by
importing them in a Catalog manner, very similar to how WFS with its
layers are now imported (except a Layer is instead a Process). Would
that be a bad solution?
This would need some new stuff:
* WPS Catalog View (a parallel to the current Catalog View, but for
external processing services, WPS or any other similar standard)
* WPS Catalog View Context Menu
* Processes View (a parallel to the current Layers View)
* Processes View Context Menu
* Specify Inputs and Outputs Dialog
The user imports WPSs in the "WPS Catalog View" -> selects a
process in
its tree -> opens the "WPS Catalog View Context Menu" -> selects
"Add to
workbench". The user selects the newly added process in the "Processes
View" -> opens the "Processes View Context Menu" -> selects "Specify
Inputs and Outputs" -> specifies inputs and how outputs should be
handled in the "Specify Inputs and Outputs Dialog". The user, again,
opens the "Processes View Context Menu" -> selects "Execute process".
