MightyMeeting becomes one of the first software offerings to support the new HP TouchPad. The vendor offers free and low-cost screen-sharing instant meeting service and competes with a crowded market of other low or no-cost screensharing services, include Mikogo.com, Join.Me, Twiddla.com and Vyew.com.

You can get started with a free account, or pay $5 per month for a Pro account which gives you up to 2 GB of storage and unlimited online meetings. Volume licensing is available for users in your own domain. There are some limitations, however: You can email or upload and share PowerPoint 2003/2007, PDFs and video files of various formats only. Launching with the HP tablet client is also an audio conference service and there is a primitive text chat feature. You can share your screen with anyone; you don't have to register with the site ahead of time.

With the new HP client, MightyMeeting shows that their focus is on mobile clients having access to these screen sharing services.
