It isn't possible under a traditional UNIX system. You need to be able 
to open a raw socket and AFAIK Rev has no way to do it. It also 
requires root access. Currently you would need the help of an external 
or other process.

Under OSX I believe there is an alternative method (never used it 
myself) that allows you to use a datagram socket rather than a raw one. 
This negates the need for root access but I still don't think Rev would 
give you access to this functionality.

Windows may be different again - not really my area.

HTH,

Andrew
