Naming ideas for an Open Source Messaging System?

Hi,
I've been working on several projects lately and one of the main ones have an Open Source Messaging System.

I'm building to includes the usual Email contents (contacts, mail, etc...), but will include the ability to add friends inside the system of which you can message (PM) and chat with.

My major problem now is trying to name it. So far I have gone through lists of names and none are available.

I've been trying to use abbreviations or short, snappy names.
For examle;
Pin-Chat(doesn't fit very well),
FusionChat(I felt it was too long),
ZIM Chat.

I would greatly appreciate any ideas or input from readers, I always have trouble naming my projects.

I think I have a good one: OpenChat
hehe
