No, it isn't. I don't think fish:// even provides any way to implement it... well, other
than polling, see below.

The KIO framework has support for notification of changes to remote file systems:
KDirNotify is a dcop/dbus interface where changes are announced; this is called by
konqueror, but this doesn't help you for changes made by others of course.

Something would have to list the fish directory regularly and compare the output,
I don't see another way. And actually KDirLister does exactly that (listing and comparing)
when it is notified of a change... so this is equivalent to -assuming- that there is a change,
regularly, in KDirLister. This would work, but it would result in a rather large
utilisation of the network and the server -- I'm not sure this is a good idea.
