No, its not worth going down that route. Possible? Yes. But not without a ton of custom written software.
If you have the money, dataq sells ethernet data acquisition devices that you can bridge to your network with a WiFi bridge. That is your best bet for going wireless and keeping your existing software (if you are using their Dll's in a custom program). If you want to keep your existing Dataq device, there are wireless USB kits but their range is limited. Addonics sells a USB to ethernet bridge which may be another alternative. There are also wireless data acquisition devices for industrial data logging that support 0-10V.
I have worked with the Dataq devices before. The dataq and arduino are not very different. The dataq has a microcontroller with a USB UART, just like the arduino. The only difference is the dataq is a finished product and is programmed for a single function along with some analog circuitry for signal conditioning. I also believe the dataq does not use a com port driver but instead a custom protocol that can be accessed via their DLL's. Its been awhile since I last worked with them.
