Well there are two now (Markus' and Paul's) .. I will try to add a third 
but need to get away from the local QRM. The plan is to use an UHF FM 
link to the remote, battery-powered site but there are some issues to be 
solved - one of them is the lack of dynamic range of the FM 
transmitter/receiver, so I may have to add some analog bandpass 
filtering before the FM modulator (which would render it useless for 
broadband VLF signals, especially natural radio signals..).
Will keep you informed, when/where another VLF 'live spectrogram' goes 
online.
Cheers,
  Wolf .
