Open Roads Designer and OpenSite

Between two offices we have OpenRoads Designer (at mine) and OpenSite (at the other). So far I'm  the only one using the software. The other office wants to check my work. I was able to cobble an SS2 version, but I guess the time has come to ask: If i make a file in OpenRoads, can someone with OpenSite open and/or view it?

I had zero exposure to what OpenRoads Designer was, and less of OpenSite. Does OpenSite have a similar configuration setup as OpenRoads? If so, can I drop in PennDOT's WorkSpace in the same way as OpenRoads? I'm guessing if so, then it should be no problem to easily open an ORD file (he said with a touch of trepidation).
