Apparently it's under construction, there is no list of features.

we're waiting for someone with a networking library to step forwards and *propose* some features!
Feel free to post some here + descriptions of any that you think are relevant?
In general, the author of the library/engine/tech needs to login to JGF and create their library entry, since that's the way they get admin rights to alter it, upload new files, add new JNLP links, etc. So...if you like the library, why don't you ask one of the authors to do this? At minimum, they just need to:
- regsiter a username + password + email
- copy/paste some details on the library
- upload a logo and/or screenshot
- create a new "release", and copy/paste in the URL to the JNLP on their site that contains that release
