Hi Robert,

BPF fills this type of need. See the Networking project wiki 
http://community.qnx.com/sf/wiki/do/viewPage/projects.networking/wiki/Filtering_wiki_page 
and the product docs.

We actually have something like this on the road map, an improved Auto 
IP which lives in "user land" and not inside io-pkt (like current 
lsm-autoip.so). If you're interested please contact your FAE. It would 
be great if you could share some of your requirements and thoughts on 
this.Hopefully it would be beneficial to you too. You can contact me at 
plahti[at]qnx.com.

Cheers!
/P
