no there isn't at the moment!
kathi is only intresting at this time for users had experiences on linux dbox2, dreambox and so on!
for normal users it isn't usable at this time, only for watching fta-tv!!!

your question about web-if:
open your browser
ht*p://yourkathi-ip
that's it

ups... forgotten you use the 30.06
there this feature didn't work!
only on 10.07!!!
