true. Note: I'd like to hear feedback from somebody who tries it. I think
you need add a link to the file lr_t.h to run the asymmetry.

possible, I really would not know. But how many analyses we have at the
same time ?

And that is beyond our control as it derives from an MIT regulation.
However I know that ernie plans to add a faster gateway machine and that
from bates we can set direct network routes to the dblast node.
For off-site and laptops i'd recommend to get a copy of the runs. This
may be painful with a slow connection but fine with at least a DSL
connection. There is a cd burner, and it should fit many flr files.
