ejabberd & pyicq - transport not showing up

Hi,

I've installed ejabberd and it's working well (except SSL, but this is another topic i think).
I've followed the tutorial to set up the pyicq transport, and on startup (python PyICQt.py) i get
=INFO REPORT==== 2006-07-13 09:31:29 ===
I(<0.1220.0>:ejabberd_listener:90): (#Port<0.1451>) Accepted connection {{xx,xx,xxx,xxxx},51184} -> {{xx,xx,xxx,xxx},5347}

so this seems fine.
But I can't discover the transport with my client (PSI), it simply doesn't show up, no messages in the logfiles.

Any suggestions for further investigation?

Thx
Quorrl
