To throw in my own loose thoughts...

9. The ability to pull files out of the stream in real-time.  e.g. If a
user attempts to download a file named codec.exe pull a copy of that
file from the tcp stream and send it to a AV/sandbox. If used with a
sandbox it would mean that, in essence, each client on the network would
become a sort of honeyclient, identifying malware during normal
activity. (of course this is of particular interest to me since I am
slowly building scripts to do something similar - though not in real
time - using our existing IDS infrastructure and some of my own rules).

10. (an extension of Matt's #2 [reputation] and Andre's 8 [language to
view app state] and my own #9) a language/protocol for it to interact
with other security devices.  Simple uses would be 'I saw X attempt to
do Y to Z so add a firewall rule to stop it X' or 'File malware.exe in
www.hacker.net/badstuff/ was identified as malware in the sandbox/AV
system so drop any packets requesting it.' Obviously this is closely
related to Matt's IP reputation scoring, but this is based upon
immediate threat on a targeted site.  This should be reciprocal also
with something like OSSEC or mod_security being able to dynamically
inject immediate information to the IDS/IPS since they can see the
interaction at the end-point after decryption.
