Sorry, I'm not aware of anything other than the passes I wrote about in the first post in this thread. Of those, the three day flexipass at 249 CHF (3 days unlimited travel any time within a month, and half-fare the rest of the month), the one-month half-fare card (99 CHF) or the Lake Geneva regional pass (94 CHF for 2 free days + 3 half-fare days, or 114 CHF for 3 free + 4 half-fare within this region, check the map on the webiste). I'm pretty sure that you can buy the regional pass yourself (from a train station, boat station, or local tourist office) and mail or give it to them when they arrive, I'm not sure about the other two - I'd ask about it at a train station for those.
