Red Cross Asks For 50 Ham Radio Operators To Fly To Puerto Rico (arrl.org) 121
Bruce Perens writes: The red cross has asked for 50 ham radio operators to fly to Puerto Rico and be deployed there for up to three weeks. This is unprecedented in the 75-year cooperation between Red Cross and ARRL, the national organization of ham radio operators for the U.S. The operators will relay health-and-welfare messages and provide communications links where those are missing and are essential to rescue and recovery. With much infrastructure destroyed, short-wave radio is a critical means of communicating from Puerto Rico to the Mainland at this time.

Yea, not really. 1200 baud packet is pretty bad for transmitting even basic information on a sustained basis. APRS use is sparse in most of the US, yet listening to 144.39 in any city shows that the channel is almost always saturated, even when there are a lot of high digipeaters and everyone is using the newer wideN-n path.
In a traditional packet network where you connect to stations using 1 or more digis (connect N0XXX via K1YYY), the channel is quickly saturated with digipeating, which gets far worse when you have hidden node problems and other collisions.
Mesh networks using modified 802.11x equipment will work better only because there's an automatic routing that takes place, but it will still suffer if there's a high node that becomes a bottleneck, and hidden nodes. At least it will be a little faster and have a decent T/R turn-around time though.
The time to build these networks is before there's a disaster, then harden the nodes. Or at least identify locations and test ahead of time but keep the equipment out of harm's way until needed. And we hams who want high speed networks on VHF and UHF need to start using what we've got (56 Ksps with QAM and other modulation, OFDM carriers, etc) and then petition the FCC for more bandwidth after we've maxed out what we have.

Even 1200 bits per second is more than even several people can type at a sustained rate. A UUCP-like system could deliver more than one SMS message per second.
In fact, UUCP is still the right tool for this job, if you're using such a slow radio link, and especially if it is intermittent. Seems like it could also handle interplanetary communications with a new protocol or two, but that's another discussion.

The problem with 1200-baud packet is that the protocol is "all or nothing", with NO forward error correction. It just keeps blindly retransmitting after pseudorandom delays until a packet manages to get through error-free.
As others have noted, packet has ALWAYS had major problems with scalability & dealing with congestion. It takes very little to saturate a packet radio link into unusability due to retransmissions & collisions.
