Well no client server is sort of not true in this case.
You can embedd Hypersonic into java applications but
they seem to opt for a jdbc approach (at least from what I could gather 
in between the lines), which basically means
that they have to sort of bridge the C code openoffice into a
jdbc bridge via jni and then they open a socket connection into
a Hypersonic server running in a separate VM in the background.
Kindof overkill unless I misunderstood the docs (who knows the 
description only mentions jdbc... so they might just leave the jdbc port 
open for others)

In the long run they probably will have to add hooks into whatever db 
interface the current system provides, KDE and Gnome both currently seem 
to move slowly towards high level db apis (thank god, given the mess 
ODBC is in Linux...)

Easy.... dont go for the packages java installs just fine without the 
debs, just get the binaries either from Blackdown or Sun (whatever suits 
your needs better)
execute the bin files and voila it expands the whole vom+jre into a 
single dir, then symlink the java interpreter into a dir of your path 
and you are done and have a running java...

Java Webstart is equally easy, just press on a jnlp file in your 
favorite browser and associate the javaws in the java bin dir with the 
file type and you are set with webstart.


Java is very clean in the resources it occupies, it basically just sits 
in a single dir ... removing it is just a matter of deleting the dir.
