owever BCHD has a 'fastsync' option that allows users to download a ~3GB file of recent BCH balances (a utxo commitment) and can be synced in a hour and requires only ~5GB of diskspace
to run.
So this is what the personal version of Member is likely to look like -
Server
------
An SQL database
BCHD node, 5GB space required
Node.js Member server
Client
------
Fat
javascript client
Possibly users will be able to set up a personal server in the cloud, and run the client app from their desktop or mobile device.
