Gps2Blue (link in my FAQ
http://forum.xda-developers.com/showthread.php?t=363431) is a freeware application that's supposed to do this also, but I haven't tested to see if it works on the Mogul.
I did a similar setup with GpsGate about a week ago, but I shared my Mogul's GPS via TCPIP using an adhoc WiFi connection and GpsGate PC version running on my laptop.
