[gtp] Protocol use

Hi,

I was just wondering how wide spread the use of GTP currently is?

I have used the protocol for my own Go program specfically so I could leave the program playing against other programs over the weekend when I'm out of the office, but at the moment the only program I can find that uses GTP is GNUGo. So are there any other GTP implementors out there or is this going to be a one boat show?

Personally I have every intention of using the protocol and leaving it in ready for a public release, as the preferred comms method, and I find it very useful for automated regression testing (ala GNUGo) and as an expert interface to the program as an alternative to simple text menus (for just playing Go).

Cheers, Jules
