So, i think it is possible to install Stellation on a window machine.
Do you agree with this ?

Yes, but there are two limitations.
First: our DB2 support is not complete. The basics of DB2 support are
working, but there are significant administrative issues in setting up
and running a DB2 server. Our group has lacked the resources to work out
all of the administrative issues. We need an experienced DB2 person to
help out with that.
Second: we provide a few capabilities that are based on calling out
to unix commands. In most places, we provide a pure Java alternative
which is significantly slower. In a couple of spots, we haven't provided
a non-unix alternative. (For example, our "svc diff" command that lists
the differences between a workspace an the repository project version
that it was derived from. The current implementation uses a unix "diff"
command to compute them.) To make those commands work, you'll need to
install something like cygwin that provides an implementation of the
Unix shell commands.
We haven't run extensive tests of Stellation under windows. I've tried
running some simple checkin/checkouts against a Unix server using a
Stellation client on a Win2K machine with cygwin installed. I haven't
tried the other commands.
If you want to try this, as usual, we'll be glad to help out in any way
that we can. The one thing we'd ask in return is that you keep notes on
whatever problems you had, and how they got solved, so that we can turn
it into a document on how to run Stellation on windows with DB2.

There are two different ways of using Stellation: as an Eclipse plugin,
and as a standalone command-line tool.
The "diff" command is for the standalone tool. So we can't use the Eclipse
diff facilities there. (Inside of Eclipse, we'll use the Eclipse diff
support.) And the Unix diff tool generates very nice context diffs that
are human-readable. Writing our own code to generate human-readable
context diffs isn't easy. And our resources have been limited, so we've
focused our attention on other things. (We are employed by IBM research,
so we've needed to focus our attention on the things that make it possible
to do research using Stellation. Spending several person-weeks writing
context diffs simply wasn't something we could afford to do.)
If someone wants to write context diffs in Java, we'd be glad to adopt
them and use them. The class org.eclipse.stellation.repos.util.TextUtils
in the core plugin contains an implementation of a diff algorithm. The
result of it is far from human readable, but it would make a good starting
point for someone who wanted to build diff support to replace our external
diff call.

Mark,
On windows , you can use such a tool like CSDiff

There's a variety of different diff tools for windows. As you as you put
one that's syntax-compatible with unix diff somewhere in your path,
Stellation will happily use it.
