Hi,

I've implemented support for TLS SNI[1] for SqueakSSL on unix. I've 
uploaded the modified source files[2][3], a diff[4], and a prebuilt 
module[5] (built on Ubuntu 14.04 from the Cog branch).
The image side code is also available[6], along with an updated version of 
the WebClient[7] package, and intermediate packages with various 
improvements[8].
The image side code works even if the plugin doesn't support TLS SNI, but 
this version of WebClient won't work with older versions of the 
SqueakSSL-Core package.
Please review the changes, and consider adding them to the corresponding 
repositories!
