I use Remote Control II (
www.wincesoft.de)which works great with my Axim 50v. I think alot of the range depends on the age of the equipment you have. On older A/V components the remote on the axim doesn't have as long of a range as newer A/V components. I have been very have with remote control II, although it is very expensive. I don't regret buying the software.
My guess is that the Nevo product will work well with the Axim.
