Question about an open source licence

[Emmanuel Lecharny <el...@gmail.com>]

Hi guys,

we are willing to use a tool to drawx some beutifull UML pictures, and 
we were loking at Poseidon UM (a tool built from Argo UML, by the 
gentleware company). They have recently changed their community edition 
licencing strategy, from a totallly free of use with a 3 monts renewable 
token, to a one year license, for open source project, under certain 
conditions, like having their logo on the web site, etc, etc. Here are 
the terms of this new licence :
http://www.gentleware.com/opensource.html

Is it acceptable? Do you think this is too much ?

I don't really care to switch to another tool at this point, I can also 
buy a licence for myself (I guess that the produced PNG, even when 
tagged by their name, are still legal to use if I have a valid licence), 
but if I can avoid spending this mony for me, and if other member of our 
community can avoid it, and be able to use the very same tool, it wold 
be a gain.

wdyt ?

I thought using a commercial tool is not a problem as long as you have the
right for its output (i.e. diagram file).  I believe no product restricts
the right of use of the output produced by its user.

So, the question would be 'is it OK to show the logo of a certain product in
our product (i.e. documentation)?'.  Hmm, I think it's quite much
considering the recent discussion on moving tool sponsor logo to a separate
page. (http://mina.apache.org/donations.html)

I personally bought a license of Sparx Systems Enterprise Architect, and am
quite satisfied with it.  Umbrello (http://uml.sourceforge.net/) and UMLet (
http://www.umlet.com/) are also great free alternatives I suggest.
