Win7 version of remote desktop is faster and much more visually attractive than LogMeIn, but a little trickier to set up for over internet use. However, since AC only runs on Windows, we already have the software.
Logmein runs on Linux, so can be useful (I can control my AC program with a Linux box). In addition, the LogMeIn non-free program has a useful file transfer feature that seems faster than Windows RD. But handwriting recognition, at least on my Lenovo tablet, won't fill in the text boxes by remote through Logmein.
I tried TeamViewer, and it is really fast and in some ways slicker than either Logmein or RD -- but in order to use the "free" version, you have to cheat and say that you are not "commercial" -- and I imagine a medical practice is considered "commercial". That one is very expensive.
I bought a CISCO router with VPN, but have never been able to get the VPN to work -- nor could my "tech advisor" who is a computer science student. I haven't pursued that, since RD works just fine, and in addition, I can use Dragon on the remote machine and fill in the AC text boxes directly on the server (without buying the "medical" version. (there are some funny glitches when Dragon is used that way, but it works pretty well). I can also use handwriting recognition on a tablet, either on remote control or when connected directly to the server.
