Just skimmed the recent entries but the "Surely You Joust" article uses a longspear as a lance (with some suggested variations of tilting lance.
No, but I also wouldn't joust without a shield.
Is there a rule covering this? Or should this be a tweak to the Mounted Combat feat?
Perhaps because the classic jousting lance is such a lengthy weapon? Still, I understand that the lances used in real combat would have been more manageable in size, sometime throwable.
A lance used in mounted combat is a specalised hold under the arm. It is only used ofr the charge and I would see no problem with allowing the use of a shield. I really see no need of special rules to permit this.No, but I also wouldn't joust without a shield.

Really depends on the culture, 'lance' can cover a lot of things ranging from an Apache warrior's javelin-like weapon to a late-medieval knight's jousting lance. I guess the question would be was there ever a lance that had a reach 10' beyond the head of the horse? I'm thinking not.
