vlc 1.0.5 linux - multiple mosaics problem

[Greendq]

Hi!
I`m running 1.0.5 on Ubuntu Karmic 64-bit.

I have the following configuration for mosaics:
---------------------------------------------------------
new bg1 broadcast enabled
setup bg1 option fake-file=/home/corsar/disk2/background.png
setup bg1 option mosaic-rows=1
setup bg1 option mosaic-cols=1
setup bg1 option mosaic-width=640
setup bg1 option mosaic-height=480
setup bg1 option mosaic-order=ch1
setup bg1 input fake://
setup bg1 output #transcode{sfilter=mosaic,vcodec=FLV1,vb=4000,scale=1,acodec=mp3,ab=96,channels=2,samplerate=44100}:bridge-in{delay=400,id-offset=1}:standard{access=http,dst=192.168.2.137:8082/stream.flv}

new bg2 broadcast enabled
setup bg2 option fake-file=/home/corsar/disk2/background.png
setup bg2 option mosaic-rows=1
setup bg2 option mosaic-cols=1
setup bg2 option mosaic-width=640
setup bg2 option mosaic-height=480
setup bg2 option mosaic-order=ch2
setup bg2 input fake://
setup bg2 output #transcode{sfilter=mosaic,vcodec=FLV1,vb=4000,scale=1,acodec=mp3,ab=96,channels=2,samplerate=44100}:bridge-in{delay=400,id-offset=2}:standard{access=http,dst=192.168.2.137:8082/stream2.flv}

new ch1 broadcast enabled
setup ch1 loop
setup ch1 input /home/corsar/disk2/1_1.mp4
setup ch1 output #duplicate{dst=mosaic-bridge{id=ch1,height=480,width=640},select=video,dst=bridge-out{id=1},select=audio}


new ch2 broadcast enabled
setup ch2 loop
setup ch2 input /home/corsar/disk2/1.avi
setup ch2 output #duplicate{dst=mosaic-bridge{id=ch2,height=480,width=640},select=video,dst=bridge-out{id=2},select=audio}

control bg1 play
control bg2 play
control ch1 play
control ch2 play
---------------------------------------------------------

Is it possible to setup ch1 to mosaic 1 (bg1) and ch2 to mosaic 2 (bg2) ?

I want to be able to serve 2 (or 3-4) different mosaics on the same port, but which are distinquished by the file name. Is it possible at all?
