I'd love to see a MAC OSX/Unix version of winbox as well.
In the meantime, I use VirtualPC by Connectix (now Microsoft) to run all of my "PC only" network apps. On slower Mac's, VirtualPC can be kinda slow, however, once it is up a running it is acceptable. I run it on a 1Ghz PPC Powerbook with pretty fair results.
One reason is that the "end user" may lose their IP address, through mis-configuration (hey, we all do that -) and need to get back again. Though experts are happy with MAC-telnet and command line, an end user might not cope if they have been only trained on Winbox.
Not everyone is a command-line genius ...
