For our 7DS project, we are dealing with a class of applications that are highly mobile, work in disconnected or intermittently connected networks, and without central servers such as DNS and DHCP.
What name do we give this new set of applications? We call them ad-hoc applications!
The only reference I was able to find for ad-hoc applications seems to suggest that this term isn't very popular, but maybe it will catch on...
Our 7DS system - and the BonAHA framework I am building at Columbia and has been put on SourceForge - will hopefully create a usable framework for these class of ad-hoc applications. We're nearly done with version 1.0, but I still need to fix up some bugs and document the code.
