Dear ECF-ers
I would like to present the output of a research project (Lead) that is
is a 3-years European Union funded research project, with
interdisciplinary approach to computer support to problem solving
activities IN THE classroom (www.lead2learning.org).

The software produced within Lead project is named CoFFEE (Cooperative
Face2Face Educational Environment); the Lead project is a 3-years European
Union funded research project, with interdisciplinary approach to computer
support to problem solving activities IN THE classroom
(www.lead2learning.org)

CoFFEE is a synchronous collaboration framework, with several tools
already designed, based on Eclipse RCP and ECF, expandible and open source.
It allows teachers to design, run and evaluate a session, made of steps,
each step resulting a number of previously configured tools that
facilitate the collaboration with threaded chat, graphical workspace, and
other tools.

Its development site is on sourceforge
(http://www.sourceforge.net/projects/coffee-soft) and its end-user site is
http://www.coffee-soft.org where documentation, tutorials (docs,video,
etc.) can be downloaded. As you can see, it is a considerable amount of
work, around 67K lines of code, that is now going open and open source (at
the end of the project, Nov. 2008). It has been used successfully in
several schools, and we plan to keep on the development, and are willing
to collaborate with other developers/researchers.

For any other info, please write to me (Vittorio Scarano) about it.

Very cool stuff Vittorio. If you have any ideas on how to improve ECF
based on your experiences, please let us know. ECF is going to 3.0 soon
and has room to expand and improve APIs based on your use cases.

Thanks!

Cheers,

~ Chris

Hi Chris,
we appreciate a lot your reply and we will happy to see CoFFEE and ECF
evolving together.
At this moment we are evaluating the future directions of CoFFEE and one
of the most interesting possibility is using CoFFEE on wireless, for
several reasons. First of all, several schools are creating new labs with
wireless lan instead of wired ones. Furthermore, the wireless context
opens new scenarios in settings different from educational: we are having
some feedback about the use of CoFFEE as support to discussion and
decision making in business meetings. In this kind of scenario we would
like CoFFEE was able to work on wireless.

Indeed, we have used CoFFEE on wireless for internal meetings, but it is
quite less stable than on wired. It seems that delays on the network cause
frequent clients disconnections (even int he absence of heavy activity).
We are using TCP containers. Can you help/suggest something about it?

Anyway, the community may be interested in the (good) results of some
stress test that we have done with CoFFEE on wired network: the tipical
test was with 20 clients bombarding the server with a rate of about two
messages per second, for as much as 4 hours...

Regards
