[Portland] event loop abstraction / libxdg-vfs

[nf2]

"event loop abstraction"-library:

I have asked Lennart Poettering from the Avahi-Project 
(http://avahi.org/) about the possibility of porting the "event loop 
abstraction" code from Avahi to a stand-alone library.  He seems to like 
the idea and says he wouldn't mind dual-licensing the code under the BSD 
license used in Portland...

(read his proposal for "event loop abstraction" in 2005: 
*http://article.gmane.org/gmane.linux.xdg.devel/6591)*

What i like about "event loop abstraction" is that you can write 
asynchronous cross-toolkit infrastructure libraries (dapi???) without 
depending on a certain IPC system.  You can just hide that IPC stuff.

For instance you can't tell from the Avahi-client-API that it's using 
DBUS internally: http://avahi.org/browser/trunk/avahi-client/client.h. 
You just have to pass an AvahiPoll 
http://avahi.org/browser/trunk/avahi-common/watch.h) pointer to the 
library. There are AvahiPoll adaptors for Qt3, Qt4, Glib2.0 and also for 
DBUS.

By the way: Here is a client-library for the xdg_vfs_gnome and 
xdg_vfs_kde executables:

Perhaps it could become part of the "dapi technology preview"...
