No. The main rotate.aprs2.net will only contain servers which do support 
HTTP uploads of positions, but it doesn't require UDP support. Maybe it 

As such I'm not a great fan of the UDP submission method due to the 
inherent security issues of UDP one-way flows (they can be spoofed since 
there's no 3-way handshake), and the classic UDP joke about the other 
person not getting it.
