[SciPy-user] problem with scipy.cow

Hey Wen,

SciPy has been through quite a bit of change since I last tested cow, and
unfortunately it doesn't have unit tests.

I'd like to look into it, but probably will not have time this week.  Here are a
few hints I can remember:

The start up process sometimes runs into troubles because of issues with ssh. I
remember debugging this by starting up individual servers on remote machines by
hand instead of using start.

Also, I'd try a simple test where you run a couple of servers on the local
machine and see if start() works in this case.  Use the actual IP number of the
machine instead of, as the loop-back address was also problematic.

hope that provides some  clues.
