As I read those docs, AnyNet is going to be replaced by something called 
Enterprise Extender which is essentially the same thing, although 
apparently better.  But it sounds like you could still run SNADS via this. 
 It actually also sounds like AnyNet isn't necessarily going away.

"The second option to consider for migrating from an SNA to a TCP/IP based 
infrastructure is Enterprise Extender technology. Enterprise Extender is a 
protocol that allows SNA application data to be transported across a 
TCP/IP network, without changing the existing SNA applications. Enterprise 
Extender is also commonly referred to as High Performance Routing over 
Internet Protocol (HPR over IP) support. With Enterprise Extender, the 
reliable transport mechanism of APPN/HPR is used to send SNA application 
data over an IP network using the user datagram protocol (UDP) which flows 
across an IP network. 

The various APPC based SNA applications including SNADS, DDM, Display 
Station passthrough, and other user supplied applications will continue to 
be supported using the future Enterprise Extender support and the existing 
AnyNet support. In addition, Enterprise Extender will also support 
dependent LU traffic when communicating with mainframe systems. This 
includes host devices (3270 DE, RJE, and program-to-program 
communications), DSNX, DHCF, NRF print and display devices, and SNA 
upstream passthrough devices, when used in conjunction with Dependent LU 
Requester support. Enterprise Extender will also support the sending and 
receiving of Alerts using the SNA/Management Services Transport support. 
Both AnyNet and Enterprise Extender allow this SNA traffic to be 
encapsulated and sent over an IP network. 

Enterprise Extender has become a more popular and accepted method for 
transporting SNA traffic across IP networks, as compared to alternative 
methods such as Anynet, due to its ease of setup, support of dependent LU 
traffic, and better performance. IBM has made a Statement Of Direction 
sharing plans for i5/OS to support the Enterprise Extender function in a 
future release. "
