I do agree here. If you are not moving a lot of data then something like BSD or Vyatta may be a good alternative. You do still have possible reboots required and things you would not see as often with a hardware-appliance model. However, for cheaper than the cost of 1 appliance you could build in redundancy. I guess the question is how many PPS you plan to push, whether you have regularly scheduled maintenance windows that you could bring it down for a reboot, and whether the additional maintenance involved still keeps you in the black?
I am a big proponent of open source every thing. Although, I am a bigger proponent of stability and less maintenance. If you could prove out a software-based solution against the cost of a hardware solution then I don't see any reason not to go that route.

Another big problem for Linux/Unix-based routers of this size/cost is
upgrade-ability. If you need to add cards, you are going to have to bring
the router down for extended periods. Likewise, a software upgrade can be
a bigger deal than on a purpose designed router. If a router is mission
critical, Linux/Unixed-based has issues over extended periods.
