Implementing GPIB support on an LPC178x

I was wondering if anyone had any experience of implementing  support for a GPIB device on an embedded system based on an LPC178x or similar. The rough outline is that an external device acting as the master and using the GPIB interface would be plugged into a LPC178x based-board via USB. It would issue commands to the board over this interface.

So there is a need to build a GPIB "driver" on the board from the ground up or find and re-use whatever existing drivers, libraries etc. are out there. Any suggestions or pointers on this would be greatly appreciated - including commercial solutions, which may be an option if the pricing is right.

I am also interested in this. I am actually interested in a bridge that would talk GPIB (IEEE-488) to legacy devices, and USB to a controlling host---I am not sure if that's also your intent or do you want to do autonomous GPIB.

There are several relevant projects along those lines:

but it would be neat if it could be done with a LPCXpresso board and a connector :)
