I'm running a total 64bit installation on my machine. So it would be a pitty
to run a single application in 32bit mode. This causes much performace issues
cause 32bit habe to be simulated.
If you don't have the time or don't have the courage to make a new plugin that
is suitable with the 64bit architecture, then simply release the source of your
plugin under the GPL oder something like that.
There would be much people giving up their free time to make a stable plugin
that works just fine with 64bit processors.
I think that if you do not do anything to solve the problems people have with
their new cpu's there will be a simillar project, that can realise the same
things as you can with your suite. But the difference would be that this
project will defenetly be under the GPL because this is really a thing that
goes on the nerves of the open source community.
And in future the amount of 64bit processors will rais.
So please develop a new plugin for this architecture or simply give the code
to the open source community.
