Not really enough information here to give any sound advice. Does she need to be in constant contact with all three at the same time or would being able to access any of the businesses at will suit the needs?
You may want to look into a VPN based solution which can be implement throught the server, if each location has one, or through small business VPN routers which run only a few hundred US dollars. That would allow her to access certain PC's/files/ect per what you setup & the network structure on the remote side. As an added bonus VPN's ,if you are not familiar, are routed across the internet securely using your existing internet connection. The only thing you may have to do if they are to be persistant connections is to up you internet bandwidth to account for the additional load being placed by the VPN traffic.
Get your facts first, then you can distort them as you please.
