Before I start working I would like to discuss the possibilities.

I would create new document in Mongo called "properties" (?) with a 
key-value structure. And two initial values, something like:

{ key: "version", value: "0.138" }
{ key: "ping_count", value: "0" }

The ping service would return this (increasing the counter every time):

{ result: "ok", version: "0.138" }

During the database migration the version number would be set.

Is this acceptable?

Thanks
