At our f2f of 2010-03-26 [1] we discussed EXI and its role on the Mobile
Web.  TimBL requested that we return to this at some point, with some
background available regarding deployment.

As the EXI spec. has just gone to PR [2] , after a successful CR, now
seems a good time to do this.

Aside for the spec. itself, the obvious starting points for a
discussion are

 1) The list of available implementations:

     http://www.w3.org/XML/EXI/#implementations

    There are only two listed, but see below;

 2) The interop test report:

     http://www.w3.org/XML/EXI/implementation-report/

    which reports on 3 (anonymous) implementations: 100% success over
    3086 x 6 tests, that is, successful transmission from all impls to
    all impls of 3086 compressed docs.

 3) The Siemens-initiated open source implementation [3] appears quiet
    -- no traffic on forum for last two months.  Hard to tell how the
    other publicly-known implementor, AgileDelta, is doing.  They have
    an EXI-based mobile development platform offering [4].  Wikipedia
    lists another open source effort, EXIP [5] which appears to be
    under active development, but not complete.

 4) There's a bit of useful info and some examples at this 3rd-party site:

    https://www.movesinstitute.org/exi/EXI.html

 5) I've sent email to the EXI WG, asking for on- or off-the-record
    information about deployment, and will prepare a summary of any
    responses I get for the meeting.

 6) If anyone on _this_ list has any knowledge of any products or
    projects which are _using_ EXI, please send pointers.

 7) Any suggestions of Web Architecture topics which the TAG should
    explore wrt potential EXI impact are welcome.
