The reason why I ask is because my work on a second life client in 
squeak stalled when every UDP packet I sent was recognized improperly by 
the Second LIfe server for some reason or another (even though the data 
portion was identical as seen via wireshark). When I tried to switch to 
a more modern squeak (I was using the Cobalt image and VM) I found that 
none of them handled https, which is needed for the initial login 
interaction and I couldn't figure out how to port the Cobalt-era 
HttpsSocket to a more modern squeak.

The upshot is that without some kind of https login, a SL viewer is 
impossible for Squeak, despite it being potentially a very good protocol 
development tool.

Resolving the UDP packet issue  is another question of course, but until 
I can log in using a modern squeak, I dont' expect anyone to try to hep 
me with an esoteric bug that only appears when talking to a single 
company's server.
