I did have a few issues with it today..  I was connected to a wireless network
and then suspended the machine (which tearsdown the wireless drivers).  When I
resumed (which reloads the wireless drivers) NM didn't notice and didn't try to
connect to my (different) wireless network.

Now, this COULD have been due to the fact that I didn't realize I forgot to
restart NMInfo, so it's POSSIBLE that that is part of the problem.  I'll be
able to test tonight when I get back to my hotel room and resume.  Looking at
the logs, however, it just resumed the DHCP and didn't notice that the AP had
gone away:

May 12 11:44:48 cliodev NetworkManager: Sending DHCP_REQUEST for to
May 12 11:44:50 cliodev NetworkManager: DHCP: Starting request loop, overall
start_time = {1115912690s, 117098us}
May 12 11:44:49 cliodev ACPI: Waking up......

May 12 11:44:50 cliodev NetworkManager: DHCP: Request sent, waiting for

Again, I'll try this again later tonight and get back to you (probably tomorrow)
with more info.

Another issue I had today was that I lost network for a short time.  NMInfo
still thought I was connected to the network, but I had no routes.  I've only
seen that one time today and have no idea how to reproduce it.

Thanks.  I'll try this.  Does NM store WEP key information in a way that doesn't
require NMInfo to run?  I.e., if I boot up in a location that requires a WEP
key (and that WEP key is already "known" to the system) will it boot up and
connect properly?  Or does the key require access to some information in the
logged-in user's homedir or something like that?
