I'm intending to be at Open Tech 2005 tomorrow. Fellow-travellers heading London-wards may want to keep an eye on the developing security situation. The BBC has a 'London alerts: at-a-glance' page.
The London Transport Tube page is best viewed (according to UKUUG) in conjunction with LT's Javascript Real Time Disruption Map (disrupted lines appear in their normal colour, working lines are shown in grey; disrupted stations appear in red). There's also a page of realtime travel news for the tube.
