I have a few Mac OS X units in remote locations (via PNT circuit, within my private address space) and I'm looking at any possible solutions for being able to gain access to my Mac machines from a windows PC. Currently for PC-to-PC connections I am using dameware. Love the programs simplicity, especially the fact that I do not need to have the host software installed prior to attempting to connect. I doubt there is anything out there that can do that exactly.
I've been looking at VNC, but it's a bit more complex to have my very much non-techie user set it up via phone.
I'm currently using webex, which is slow and a pain in the behind.
I'm open to suggestions, freeware or payware, I don't really care.
