Yes they are, however they are still detected via udev and require a
proper modem driver. 'atmodem' is a collection of atom drivers that
implement generic 27.007 functionality. The difference should be
explained nicely in the presentations posted on the site.
See the calypso modem driver in plugins/calypso.c for an example as well
as doc/calypso-modem.txt for an example udev rule.

A udev rule like:
KERNEL=="ttyS0", ENV{OFONO_DRIVER}="your_driver"
should be all that is needed.

Yes all the things you have listed are possible.
