Comment(by elb):

 If I understand this patch, it is not reasonable.  There should not be a
 user-visible setting of "UDP" as a proxy type for all accounts -- for
 everything but QQ (and ICQ protocols we do not support, and may not even
 exist any more), that is meaningless.  The user should not be presented
 with meaningless options which are guaranteed to fail.

 The choice between TCP and UDP doesn't map to a "proxy type" in most
 cases; generally, protocols are different between TCP and UDP even for
 services which support both.  (E.g., UDP requires application-level
 retransmissions, etc.)  If parts of the purple_proxy framework can be
 broken out to better support UDP, great, do that -- but the connection
 should probably be via purple_proxy_connect_udp or similar, rather than
 trying to shoehorn UDP into the existing proxy framework.  Protocols
 ultimately have to make the decision of whether to use UDP or TCP.  There
 should be, in this case, a checkbox somewhere in QQ account settings for
 "Use UDP"; when it is checked, QQ should use UDP rather than TCP, along
 with whatever attendant protocol changes that incurs (if any).  It sounds
 like this is what is happening now, you just want to push some of that
 code into libpurple.  That's fine, but do it in parallel.

 Hope that made sense.
