Should be simple since the functionality of the OSD is already available
in the code - you just have to make it usable via svdrp. This could make
a powerful interface to web-or-whatever-gateways or fancier remote
controls ;-)

Thre following patch implements the commands DELR (delete recording) and
LSTR (list recording) into svdrp. Hope it helps.
