Too bad I didn't attend code4lib.  OCLC Research has created a version of MARC in JSON and will probably release FAST concepts in MARC binary, MARC-XML and our MARC-JSON format among other formats.  I'm wondering whether there is some consensus that can be reached and standardized at LC's level, just like OCLC, RLG and LC came to consensus on MARC-XML.  Unfortunately, I have not had the time to document the format, although it fairly straight forward, and yes we have an XSLT to convert from MARC-XML to MARC-JSON.  Basically the format I'm using is:

[
  ...
]

which represents a collection of MARC records or 

{
  ...
}

which represents a single MARC records that takes the form:

{
  leader : "01192cz  a2200301n  4500",
  controlfield :
  [
    { tag : "001", data : "fst01303409" },
    { tag : "003", data : "OCoLC" },
    { tag : "005", data : "20100202194747.3" },
    { tag : "008", data : "060620nn anznnbabn          || ana     d" }
  ],
  datafield :
  [
    {
      tag : "040",
      ind1 : " ",
      ind2 : " ",
      subfield :
      [
        { code : "a", data : "OCoLC" },
        { code : "b", data : "eng" },
        { code : "c", data : "OCoLC" },
        { code : "d", data : "OCoLC-O" },
        { code : "f", data : "fast" },
      ]
    },
    {
      tag : "151",
      ind1 : " ",
      ind2 : " ",
      subfield :
      [
        { code : "a", data : "Hawaii" },
        { code : "z", data : "Diamond Head" }
      ]
    }
  ]
}
