You didn't specify WiFi - only network -> IR. But, I communicate with a GC-100 from my PDA or laptop via a wireless router so while, the need for a network cable may restrict where the GC-100 can be located, it can be reached by WiFi.

If Philips were to enable the iPronto to send TCP/IP strings to any IP address, it could also communicate this way and become more than a pretty[,] expensive paperweight. [comma is optional]
