As I recall (it's been a while since I read that article), the author 
mentions having considered hacking together an approach using a standard 
cell phone, but decided it wouldn't provide the physical robustness of 
the MultiTech cell modem (which can be properly mounted, and is designed 
for enterprise reliability).

That sounds like an accurate assessment, but the budget solution might 
still come in handy in some situations. Consider, for example, that if 
the software and compatible phone hardware has already been figured out, 
you could add out-of-band notifications for the cost of a phone ($20) 
and pre-paid plan ($100/yr). (Although as I recall the "telemetry" phone 
service the author purchased only cost $120/year. So really the savings 
is just in convenience (phone and pre-paid service can be bought 
anywhere) and hardware. It'd be more of a bargain if you could put 
multiple phones/SIMs on a single pre-paid plan.)

Has anyone tried it?

Looks like reference material is pretty easy to find. In addition to the 
article mentioned earlier in this thread:

A Freshmeat.net search on SMS turns up several projects that all use 
gnokii as their underlying interface to the cell phone:

http://en.wikipedia.org/wiki/Gnokii

   Gnokii is a suite of programs for communicating with mobile phones. It
   was initially only available for Nokia mobile phones, but later
   extended to support others. It is available for Linux, BSD unix,
   Windows and Mac OS X and as source code.

gnokii was actually pretty easy to setup on my Ubuntu laptop after about 
30 minutes of mailing list mining and wiki reading. First I peered my 
Nokia 2760 via Bluetooth with the laptop. (Using a USB cable is most 
likely far more reliable.) I installed gnokii:
% sudo aptitude install gnokii-cli

Copied over the template config:
% cp /etc/gnokiirc .gnokiirc

Then I ran a command to determine my phone's hardware address:

% hcitool scan
Scanning ...
	00:1F:5D:38:37:3F	Nokia 2760

Then edited .gnokiirc to contain:

[global]
port = 00:1F:5D:38:37:3F
model = 6510
connection = bluetooth

(leaving everything else as it's default.)

Tested connectivity:
% gnokii --identify
GNOKII Version 0.6.26
IMEI         : 011796000826966
Manufacturer : Nokia
Model        : RM-391
Product name : RM-391
Revision     : V 06.83

Sent an SMS (using text dialogs):
% sendsms

Or this works too:
% echo "message" | gnokii --sendsms 6175551212
GNOKII Version 0.6.26
Send succeeded!


gnokii has a library interface Perl bindings, so you can more tightly 
integrate it with your network/system monitoring tools.
