So the requirements doc says the application must support WMS, WFS, WCS and WTS. I hate the first three, but the four one confused me. I was unaware of WTS and Wikipedia is zero help. A phone call into the contracts person (who has no idea what GIS is in the first place) was zero help. She did say that she’d get back to me later today to find out.

UPDATE

WTS means “Web Tile Service”. It’s not WMTS but something they just made up. There is some sort of 900913 awesome in that. I’m just a bit afraid to ask the XYZ order…
