Missing from almost every calendar hosting thing I've used is the ability to publish free/busy information to allow others to schedule me into meetings without needing to be on the same system.

I'm pretty sure vCalendar supports this, just no one has implemented it.

If I could host a lightweight javascript app that let you browse the information until your client supports it properly that'd be cool.

Lotus Notes had that. Administrative staff could look at your calendar and sign you up for things..

Of course all Notes Mail and Calendar are just Notes Applications built upon its nosql database and lotus script. Its why they were kinda awkward. But I worked briefly at IBM making custom business Apps with Notes, which was a decent/ fairly easy way of making custom applications for businesses last century.

I use claws mail for this. I get invites from caldav and reply directly in my mail client. Cal views are primitive.
