I've been using hamachi and cobian backup to remotely backup my servers in the two offices for about 6 months, it works well.
For some reason, I never tried to directly connect AC until yesterday.
I must admit I was using a slower machine, but AC seemed to take a long time to load and connect as well as open charts, although it did work.
I will play with it more and give a report. I would like to try with a machine faster than 1K and see if I have better results.
The 1K machine works fine on a wired Cat 5 network. I suspect it (hamachi) will be too slow to be very practical.
I use Log Me In a lot between the two offices. I have 5 pro subscriptions but have the other computers with free prescriptions to do background tech stuff.
