Next jabber slot May 4th

No one objected and some seemed to like the jabber thing
so can you try to keep May 4th, same time free for a
jabber meeting.

Time is 1500 GMT, 0800 Calif., 1100 New York, 1600 Dublin,
1700 Berlin, and once more apologies to everyone else.

Duration is nominally 1 hour.

Agenda to be set near the time when we see what's a good
topic to pick.

Stephen.
