reusing existing coax for ip cameras

[cdrracing]

My client has 5 everfocus cameras (and dvr) as well 4 IP cameras. He's wanting to convert everything over to IP. The everfocus cameras are running on coax cable and are far enough away (on the shed, on the light pole, etc) that makes it nearly impossible to pull new wiring.
Has anyone had any luck converting ethernet to coax? If so what do you recommend?
Also, is there a maximum length when converting to coax?

Expensive but can be done...http://www.veracityglobal.com/products/ethernet-over-coax-devices/highwire.aspx

On the subject of EverFocus: I found this on craigslist the other day, it's good for a few laughs.

In many situations, running new cable is more practical. Reusing the coax is what the TVI, CVI, and SDI. People here aren't too kind to these formats, I'd lost track of the difference between some of them but found this: http://www.security-camera-warehouse.com/knowledge-base/hd-sdi

I'd choose to invest in IP cams and new cable.
