  I've been doing some rough drafting on PIC history for the generic
template.  Most of the early stuff is pretty straightforward to detail.
Lessons learned is different.  I realize we've never discussed nor
set down on paper exactly what we think we've learned.  Beyond the
generic template, we've discussed the value of a 'lessons learned'
paper on its own.

  I'd like to crank up at least of list of learned items we
mostly agree on and solutions where the items represent problems, if
possible.  So, here are ten to start.  More?

1)      802.11 is problematic for VoIP.

2)      Much better, more net friendly codecs (e.g., iLBC) are needed.

3)      We want to locate the user, not a communications device.  So,
        the scanned device needs to be worn or always carried (e.g.,
        a PDA, a cell/wifi phone.)

4)      The ideal target device may not be a laptop.

5)      There is a critical need for a high quality, open source SIP UA.

6)      Fine grained, high quality weather reports would be highly
        valuable.

7)      Line item portals and maps have complementary values.

8)      Versioning is important.

9)      Initially, users really have no idea how to deal with PIC/ALS.
        The dominant reaction is confusion.

10)     Wired headsets aren't ideal.
