SWS 7.0U1 Custom Session Store

Question

Is there a way to write a custom session store for SWS 7.0U1? The documentation seems to state that there is a way and the DTD shows a type of 'custom' as an accepted type, but there doesn't seem to be any other information about it. If I attempt write something implementing the SessionDataStore that comes in the examples directories the IWSHttpSession class seems to be not available to build again.
Is it where I have to go back and write against the even more deprecated IWS 6.0 Session Manager codebase and plug my own Session Manager in there if I don't want an in-memory, File or JDBC based Session Manager or Session Store?

Yes, that document. Under where it says :
"File Session Manager
The file is another file-system-based session manager provided with Web Server. For session persistence, file can use a file to which each session is serialized. You can also create your own persistence mechanism."
I was assuming that the "You can also create your own persistence mechanism." meant something along the lines of being able to look at the FileStore.java example code and then create a MemcachedStore.java and possibly somehow use the 'custom' type as defined in the DTD (sun-web-app_2_5-0.dtd) for persistence-manager and possibly a class definition and that _store would be used by the Session Manager to store off the sessions. The problem is that when compiled against the webserv-rt.jar that comes with SWS7.0U1 it says that IWSHttpSession is unavailable.
So now I'm assuming that you pretty much just have to go and create a MemcachedSessionManager along with a MemcachdSession and plug it in there utilizing the deprecated IWS 6.0 mechanism.
