Thanks to Resource Shelf, I’ve seen a posting about Zoho Meeting.  I’ve been a bit of a fan of Zoho (as opposed to Google Docs) for some time now, and if this is good, I shall be glad of it.  The idea of being able to do low-cost web-conferencing is something that appeals to me, especially for training.  And even more, not being a google site, it’s less likely to be blocked by corporate firewalls for now.  Something to watch.  I’ll be interested to read what others are doing with it.
