Gadget on the XS - upwards/downwards compat?

[Martin Langhoff]

Hi Daf & Collabra team,

Michael Stone gave me a brief run down of Gadget and plans to review
it for inclusion on future XO and XS builds. What he described sounded
pretty good, so I am keen on this.

Have you guys considered backwards / forwards compat? We have many
locations where XS and XO will be updated on separate schedules -- can
an old client talk to a Gadget-driven server? How about vice-versa?
Can old and new clients coexist?

chees,
