Is there an easy way to create XREF's by using IDC or a similar mechanism?  For example, say I know a particular function is called throughout a program via a function pointer in some standard way.  How could I write an IDC script to go through such that when I looked at the code for the function, I'd see all the places that referenced it (i.e mark the appropriate "call eax" so that the IDA knew that it always called function foo)?

How about

AddCodeXref(ScreenEA(), LocByBName("foo"), fl_CN);

Just position the cursor on the call eax instruction and issue the above IDC command either via File>IDC Ccommand... or using the IDC command line tool.  There are a variety of ways to try to automate this further, but the statement above has all of the basic elements that you need.

Awesome thanks.  That's plenty to get me going.
