Remote application deployment w/COM+

I have a client/server application and am wondering if there is any way to deploy it across the internet. The client application basically works by calling methods on remote objects (created though the CreateObject method using the ServerName argument) that are hosted in a COM+ application on the server. For example:

Set objSomething = CreateObject("MyDll.MyObject", 168.0.0.1)

Since the ServerName can just be an ip address, is it possible to connect to a server not on my network (i.e. connect through the internet)? Just wondering if anyone has tried this, and what the loss might be in performance. If I could set this up, it might allow my users to work offsite. I'd appreciate any input anyone had.

I believe it is possible, however it means opening up the server to
the internet. It would be an (easy?) target for hackers because
of the windows protocols exposed (like RPC).

Definitely a good point. I'm guessing though that COM+ only uses a couple of tcp ports, which I could open up on a firewall (which is a crude solution, but might work). Security is something I would have to investigate, assuming I could get it work at all.
