I think so - you could send high volumes of packet traffic to a bulk relayfs channel and read it from the mmap'ed relayfs file in user space. The Linux Trace Toolkit does the same thing with large volumes of trace data - you could look at that code as an example (http://www.opersys.com/relayfs/ltt-on-relayfs.html).
