Using SignalTap with a device configured by an external processor?

As our FPGA is not connected directly to the PC, SignalTap doesn't see the hardware. I guess we would have to write a program on the external processor which would present data generated by the signaltap instance back to the PC. My first thoughts were that this probably isn't worth the effort given that I can always re-write my code to present signals to IO and then view them on a scope. There is a reasonable amount of work involved in this however as we are structuring our code as custom components within SOPC Builder and there are >50 signals we wish to observe.

Still this is the way I will go, unless someone has gone through the process and knows of e.g. any freeware which would perform this task? Or alternatively if you tried it and found it to be unworthy of the effort, please let me know as well.

Thanks again
