actually, we (meaning christoph, niko and me) considered to port TMNav int=
o beeing an eclipse application some time now. I was actually against that=
in the beginning but started doing a portotype because i wanted to how ho=
w difficult this would be. I never got into more than showing some maps, a=
n index and a Renderer (Touchgraph, there are some problems with hypergrap=
h and the SWT=5FAWT bridge which i never got into solving) - much like the b=
asic structure of TMNav. If you are interested, just tell me :).

Well, i am a little confused here mayself, the 3 tier application "pattern=
" is typically used for serverside apps, wheras GUI aps are normally only =
build on the MVC pattern.

Well actually i do not think that this seperation would make much sense fo=
r a GUI app (much more an eclipse based app), however i think that the lay=
ers could be drawn something like:
Presentation Model layer (Displaying the Graphmodels->Touchgraph libraries=
)
^

Business Model layer (Building graphlike abstractions from the TM ->Pa=
nckouke)
^
|
Database layer (TopicMap engine)
^
|
Database (TopicMap Data)

Are you allowed to tell us what you want to do / what kind of data you wan=
t to display and in which way =3F
