Disclaimer: I haven't looked at the server for kaillera! Now, it might be possible to launch the server using a series of send keys and/or mouse clicks, but it would always pick the first server on the list. I don't think there's any *clean* way of adding this software. Like HK said, if you have to pick a server manually from a list, you would either need to write a script to do it automatically or come up with some kind of other similar solution (plugin?). Either way, it looks pretty messy which basically defeats the porpose of the front end (making things look clean). Perhaps you could suggest that the authors of the emulator incorporate the server list into MAME similar to how MAME now has a list of roms included? You load up the software and it brings up a list of servers. Anyway, that's my uneducated input.
