Can I write an OpenShift Origin app that can ingest UDP traffic on an external port?

Question

How generic of a PaaS is OpenShift Origin? From looking at the architecture overview, it seems very web-centric. Can I use OpenShift Origin to build a private cloud where I can run arbitrary apps, not just web-based apps?

As the title of my post indicates, my pressing question is whether it is possible to create an OpenShift app that can open a socket and ingest UDP traffic -- I don't need (and don't want) an haproxy for this app, and I don't want all the UDP traffic to first go through the node host's proxy.

Essentially, I'd like to know if I can deploy an app to a node, and have that app be able to receive UDP packets from an external-facing port on that node. Is this possible?

The RedHat docs, Configuring the Port Proxy, make me think this isn't possible:

applications listen for connections on the loopback interface. The node runs a proxy that listens on external-facing ports and forwards incoming requests to the appropriate application

I'm hoping there is a way around this restriction. Would a custom cartridge work?

As far as I know thats not possible at this time. However I would suggest asking the developers for Openshift origin on either the mailing lists or you could check on #openshift-dev on freenode.
