Michael & Janine,
Jabber can be used as Michael suggests, the apm package I wrote shows examples of this type of use. However, I would agree with Janine in that it is quite a hack, and very ugly. Why would someone choose to operate by typing in commands instead of clicking on a link or button, assuming both were available? Maybe the point is that you cannot click on a mobile device? I don't know about that. As a protocol, Jabber is not more reliable than HTTP, but rather less. If you need reliability for disconnection, email would be the best, since it was designed for intermediate storage of messages. Jabber will store messages at the receiver end, but that is probably where the component is located anyway.

Your summary looks great, any word on the data model to support this?
