So a few questions...

- Where's the IS-707/IS-856 support?  Yes, many operators will be
transitioning to LTE by 2015, but there are 450 million CDMA subscribers
right now [1], and that number is expected to grow.  Having two modem
control stacks simply isn't an option.  Not having designed support for
CDMA into the service seems pretty short-sighted.  I know Nokia itself
doesn't care about CDMA any more, but still...

- GPS support?  In reality, there can only be one service arbitrating
access to modem serial ports, since not all serial-based modems provide
more than two ports, and one of those must be used for PPP, and the
other for signal strength, etc.  Logically, the service controlling
these ports for cellular should also be handling GPS requests on these
devices.

- Is there some reason we cannot coalesce around *one* userland cellular
service?  There's Wader/VMC (python+dbus) and ModemManager (C+dbus) and
gsmd (C+dbus) already; it seems that for the sake of users, it would be
great to concentrate that effort in *one* place so that we don't have to
keep quirking every single modem in 4 different places.  TBH, I don't
care which one it is, as long as (a) it has a sane D-Bus interface, (b)
it supports CDMA, (c) it uses DeviceKit, and (d) it's GPLv2.
