Big Pouch
It's big but with pouchdb, you need to use erica to put it into couchdb (doesn't work in cloudant), and your slides are just docs with the set up
{
"_id":"1",
"text":"slide"
}
and then incriment the ids
after you update the slides you need to run replicate()
in the console.
There is a command line util you can also use,
bigPouch new "slide content"
bigPouch get 4 #slide number
bigPouch update 4 #slide number
bigPouch len
