[kepler-dev] remote display of Kepler & drag&drop

Hi everybody,

Just a small comment about this topic from my side: Some time beginning of
this year (I don't know if something changed in the meantime) I also tried
to run Kepler remotely via ssh (100 Mbit/s connection) from a Linux box
(with Kepler) to a Mac (with the display) and it turned out to be very slow,
so that it was impossible for me to work like this (though I don't remember
if I also experienced the same specific problem as described below).
However, I routinely run another Java program (Eclipse) in a similar
setting, which is a little slower than running it locally, but I can still
work without problems. It would considerably ease my (and probably also
other people's) work when it would also be realistically possible to run
Kepler remotely via ssh, since at least for the Resurgence project several
external codes need to be installed (Nimrod, GAMESS etc.) that you often
only want to have installed on a server and not on user machines. Also, it
would make it easier for users to apply Kepler, since they would not
necessarily need to install it on their local machines before being able to
start playing :-)

Just my two cents,
