Looking at the screenshot(s), it seemed to be quite overly complicated.
You also have two buttons in the toolbar with the exact same icon. And
another icon is scaled up from a smaller version to fit the toolbar's
icon sizing. The HIG also recommends very strongly against the use of
tabs. As "Projects" stand, I don't see how the terminology makes any
sense to be associated with transferring files. It would probably be
much more useful to group things by server in a treeview, rather than
having a bunch of tabs, automatically.

Uhm. I highly doubt you are going to be running a daemon on a remote
webdav or ftp store. You certainly aren't going to be running one on I think you missed the entire point of my paragraph, which was
to say that you can transparently transfer things from one remote box,
to another. It has nothing to do with a daemon on a remote machine,
other than the fact that it completely removes the need for such a

But you need to handle the fact that the display is not the same. It is
very easy to shove the list of downloads in an xml file, and have some
watch set on that file so that whenever it changes, all running daemons
get the updates. It's basically the same way a cache system works.

But I've already done 90% of the gnome-vfs and bonobo stuff? Why should
I "switch" and let you do it all again from scratch, when you clearly
don't have the experience with gnome-vfs and maybe bonobo needed to do
it right? Switching to gnome-vfs is NOT EASY. I can't stress that
enough. Managing queues and dealing with the async API and lots of stuff
is just not fun. There is the other problem of the fact that the async
vfs API is not cancellable, afaik. I'm also not sure about the resume
abilities of gnome-vfs. This is nominally why emphetamine does neither
of these correctly yet. It kind of does cancelling, but it frequently

And what exactly is the problem with something else being done inside
gnome-network? There are many download manager to choose from. Is there
some particular disgust you have with mine?

Comparitavely speaking, from experience, the UI is definately the easy
part of a download manager. If you don't want to be sluggish, then the
communication needs to be asynchronous.
