Is this KDEish enough ?

http://www.neundorf.net/pics/swriter_gimp_fuse-kio-gateway.png

(it's 700 kb big, maybe somebody could mirror it somewhere).

What you see in the picture:

konqy showing fish://alex@marathon/home/htdocs/

via "Open with" and the attached desktop file I opened olaf190.jpg with gimp 
and main.html using OOo swriter :-))

This can be verified by the output of ps -ax|grep gateway in the konsole on 
the upper right corner. You see the fuse_kio gateway process, and the gimp 
and swriter processes accessing files located under the mountpoint given to 
fuse_kio :-)

In the lower right corner you can see the debug output of the running 
fuse_kio.

How to do it ?

Install the attached desktop files. They feature a modified Exec entry

Exec=ioslave_helper gimp ]placeholder ]url %u

The ioslave_helper script checks if there is an url given after "]url". If 
yes, it modifies the url so that it points to a local file accessible via 
fuse_kio. If it is already a local path it doesn't change it. It then puts 
the modified url at the position "]placeholder" and then starts the app 
(first parameter).

ioslave_helper is a ruby script. Maybe somebody wants to translate it to perl 
or shell ?

It relies on the fact, that the environment variable 
FUSE_KIO_GATEWAY_MOUNTPOINT is set correctly. Set it e.g. in startkde or 
before you start kde, and then start fuse_kio once kde is running:

export FUSE_KIO_GATEWAY_MOUNTPOINT=/your/mountpoint
...
startkde
...
fuse_kio --gateway $FUSE_KIO_GATEWAY_MOUNTPOINT

And then open your favorite remote files from konqy with "Gimp fuse" and "OOo 
writer fuse" :-)

The script is also in kdenonbeta/fuse_kio/ioslave_helper
