priceline - name-your-own-price

We're going to fly between SFO - LIM, and are thinking of Priceline's
name-your-own-price (NYOP)

Priceline says that unless you specify otherwise your flight will have
at most one connection.

However, for international flights, there's no maximum specified
layover time, as there is with domestic flights. (I sent them an email
on this). On their web site they say that the longest layover to
South America is 5 hours, but, given the email I received, I take this
to mean the longest layover there HAS been, not the longest there CAN
be.

Does anyone have experience with NYOP on international flights?

Also, do you get presented with a choice of flights or just one? I
mean, it could be possible that several airlines would meet your
price.

TIA.
