We've done exactly this to reduce the cost of phone lines to people's 
desks, modems, etc.. We use an application proxy firewall and simply 
connect Compuserve's port through the firewall. Functionally, it works as 
expected. Performance, though, doesn't seem much faster that through one 
of their dial-in ports.

>From a security standpoint, the connection is one-way, and I don't expect 
any unique security concerns that don't already exist with providing 
access to other services.
