In my opinion, it depend of the nature of your module. This is true if 
your module is strongly linked (library bound to the code). If the 
module is communicating through a network socket using the XML protocol, 
I think you can provide a proprietary implementation.

Yes. If it were not the case, you would not be able to use 
infrastructure software through the network and would have a problem 
with GPL STMP server (you could not send mail with Outlook for exemple) 
or with FTP server (You could not use a proprietary software to upload 
So, I think there is no problem.
