I spent the last 4 days in an area with limited cell coverage and few open wifi hotspots. I learned that #xmpp works and works well in these conditions. Pump was worthless up there as it never loaded my stream, Impeller & the web browser worked about 1 time in ten. My xmpp client never missed a beat. xmpp even beat email under these conditions. I may setup an SN fed with xmpp support and be done with trying every new fangled social networking gizmo that comes down the pike.
