Tungle Meeting Scheduling Service

I have been trying out Tungle a web based public meeting scheduler.  Apart from the vaguely naff name (or is that just me?) - it looks an interesting service.  You can consolidate several calendars (all mine are google calendar based, but across multiple google apps accounts) and then publish an online schedule that contacts external to your organisation can browse, select a range of possible meeting times and dates and then send you meeting requests, which you can then respond to.  There is also an iphone app for this service.  I would definitely use a service like this, it just remains to be seen whether my contacts will.  I will report back how I get on.
