[RDD] Synchronizing carts and logs

I'm not comfortable playing linear audio files across the Internet,
particularly from either Cape Cod or Block Island, where available
bandwidth can vary wildly. The Block Island station runs rdairplay on a
machine at its transmitter site with local audio and a local database,
precisely to avoid dropout issues.
On the island, Verizon DSL or mobile broadcband from Verizon or AT&T are
the only Internet options, and my understanding is that they all connect
to the mainland Internet through a common (Verizon? ) microwave hop whose
capacity is adequate for the island's year-round population of 1,000, but
less so in the summer when it baloons to 10,000 or more.
Cape Cod may have a similar problem; our Comcast service there is
nominally 20 Mbps (IIRC), but there are times when we have horrendous
dropout problems when live audio from my client's Hyannis studio is routed
to his Framingham (Boston) station. Those live broadcasts are either 64
Kbps HE-AAC or 128 Kbps MP3.
Re: replication: neither the Hyannis nor the Framingham database can be a
slave of the other. There are audio carts produced in Hyannis that run in
Framingham and vice-versa. In theory, someone can record a newscast or
feature and expect it to air 15 minutes later at the other facility.
The scripts we have work; my only issue is minimizing the headache at
Я там, где ребята толковые,
Я там, где плакаты "Вперёд",
Где песни рабочие новые
Страна трудовая поёт.
