Hi folks -- just wanted to mention that I have recently launched an SMS service for DCist.com that relies heavily upon Gammu.  Although throughput is quite limited, it's been a good fit for our traffic levels, and I have been quite impressed with the setup's stability.  You can find the announcement post here:

And I'll be writing up a detailed how-to of my configuration in the near future.  I'll be sure to let the list know when that happens.

I'd like to express my thanks once again to the folks on this list for all the help you provided me with.  Michal and Marcin went to great lengths to help me get Gammu up and running.  Two phones and four cables later it finally did, and I'm now quite a happy user.
