Hi Karl,

Glad to hear it is working well.

On your point about economic sense, I quite like this quote from Sir
David Attenborough in front of some UK committee:

> Sir David Attenborough: I grew up during the war and during the war it

Computing, and networking in particular, is front and centre when it comes
to the wasteful use of electricity.  It's the weekend, and yet every
ethernet switch runs as though it is facing peak load, just so you get
this e-mail milliseconds earlier.

Cheers, Glen
