The workaround is a win32 executable 'UPnP-Inspector-0.2.2-1-setup.exe' stored on the coherence project's web site:
and referenced by a link in the hummy.tv wiki:
https://wiki.hummy.tv/wiki/Download_Sta ... t_USB_Copy
I checked the executable for malware at
which reported that 2 out of 65 malware engines (Baidu and eGambit) detected anything awry:
I then checked at the hummy.tv forums to see if anyone had flagged upnp-inspector as a malware risk - and found none.2 engines detected this file
File name UPnP-Inspector-0.2.2-1-setup.exe

So I went ahead and installed the executable using 'Open with Wine Windows Program Loader'. Upnp-inspector installed without throwing any errors, and then appears under 'Menu > Wine'.
It runs fine, and lets me browse my home video servers and upload and stream videos from them using wget and a video's URL (as explained in the hummy.tv wiki link above).
Hope this helps others!
