PopNote is a lightweight yet robust peer to peer Instant Messaging communication client that works over the Internet or LANs. PopNote can send an instant message that will pop up on the destinations Desktop on arrival; or allow more aggressive real time chatting. The inherent beauty of a PopNote is it does not demand an immediate reply as is the case with real time chatting. In other words, a received Pop Note can be minimized for later disposition, or answered and returned back to the sender immediately
